Aleph ~ The first letter of the Paleo-Hebrew pictograph (ox head) meaning strong, power, leader.

It is said that Aleph (or alef or alif, transliterated ʾ) is the first letter of the Semitic abjads which is a form of writing as well-adapted to the morphological (the study of words, how they are formed) structure of the Semitic languages it was developed to write. However, it's etymology is stemmed from the Paleao Hebrew and cultivated from the time of the Sumerian culture. 

Aleph is often transliterated as U+02BEʾ, based on the Greek spiritus lenisʼ (smooth breathing); for example, in the transliteration of the letter name itself, ʾāleph.

The name aleph is derived from the West Semitic word for "ox" (as in the Biblical Hebrew word Eleph (אֶלֶף) 'ox'), and the shape of the letter derives from a Proto-Sinaitic glyph that may have been based on an Egyptian hieroglyph, which depicts an ox's head.

In Modern Standard Arabic, the word أليف /ʔaliːf/ literally means 'tamed' or 'familiar', derived from the root |ʔ-l-f|, from which the verb ألِف /ʔalifa/ means 'to be acquainted with; to be on intimate terms with'.[6] In modern Hebrew, the same root |ʔ-l-p| (alef-lamed-peh) gives me’ulaf, the passive participle of the verb le’alef, meaning 'trained' (when referring to pets) or 'tamed' (when referring to wild animals); the IDF rank of aluf, taken from an Edomite title of nobility, is also cognate.

The first letter of the Paleao Hebrew alphabet in marking the beginning specifically in the context of the consecutive order of letters. Gr. archē (properly abstract) a commencement or (concrete) chief (in various applications of order time place or rank): - beginning corner (at the) first (estate) magistrate power principality principle rule. This is opposite of the translation of the paleo Hebrew term Resh that means first. The (Phoenician) Palaeo Hebrew variant gave rise to the Greek alpha (Α).

Characteristics of Aleph ~

Beginning ~

John 1:1-5, 14

"In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not. And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth."

1 Peter 1:3-5 (new beginning)

"Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead, to an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you, who are kept by the power of God through faith unto salvation ready to be revealed in the last time."

Leader ~

Proverbs 16:7, 9

"When a man's ways please the LORD, he maketh even his enemies to be at peace with him. A man's heart deviseth his way: but the LORD directeth his steps."

1 Timothy 3:2-7 (Pastor)

"A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach; not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous; one that ruleth well his own house, having his children in subjection with all gravity; (For if a man know not how to rule his own house, how shall he take care of the church of God?) not a novice, lest being lifted up with pride he fall into the condemnation of the devil. Moreover he must have a good report of them which are without; lest he fall into reproach and the snare of the devil."

Strength ~

Isaiah 40:31

"But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint."

2 Timothy 1:7

"For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind."

The Psychology of Aleph ~

Psalms 119:1-8

ALEPH. Blessed are the undefiled in the way, who walk in the law of YHWH.

Blessed are they that keep His testimonies, and that seek Him with the whole heart.

They also do no iniquity: they walk in His ways.

Thou hast commanded us to keep Thy precepts diligently.

O that my ways were directed to keep Thy statutes!

Then shall I not be ashamed, when I have respect unto all Thy commandments.

I will praise Thee with uprightness of heart, when I shall have learned thy righteous judgments.

I will keep Thy statutes: O forsake me not utterly."

Omega ~ The last letter of the Greek language meaning "end"; mathematically representing infinity.

The final letter of the Greek alphabet, c. 1400, from Medieval Greek omega, from classical Greek o mega "big 'o' " (in contrast to o micron "little 'o' "); so called because the vowel was long in ancient Greek. From o + megas "great, large, vast, big, high, tall; mighty, important" (from PIE root *meg- "great"). Used figuratively for "the last, the final" of anything (as in Revelation 1:8) from 1520s.

As the final letter in the Greek alphabet, omega is often used to denote the last, the end, or the ultimate limit of a set, in contrast to alpha, the first letter of the Greek alphabet; see Alpha and Omega.

Alpha (Α or α) and omega (Ω or ω) are the first and last letters of the Greek alphabet, and a title of Christ and God in the Book of Revelation. This pair of letters is used as a Christian symbol, and is often combined with the Cross, Chi-rho, or other Christian symbols.

The first written record we have of the phrase "alpha and omega" is from some old manuscripts of the Christian New Testament.

The phrase "I am the Alpha and the Omega" (Koiné Greek: "ἐγώ εἰμι τὸ Ἄλφα καὶ τὸ Ὦ"), is an appellation of Jesus and of the Father in the Book of Revelation (verses 1:8, 21:6, and 22:13).[2] The first part of this phrase ("I am the Alpha and the Omega") is first found in Chapter 1 verse 8 ("1:8"), and is found in every manuscript of Revelation that has 1:8.

Alpha (Α) and omega (Ω) are the first and last letters, respectively, of the classical (Ionic) Greek alphabet. Thus, the phrase "I am the alpha and the omega" is further clarified with the additional phrase, "the beginning and the end" in Revelation 21:6, 22:13. The first and last letters of the Greek alphabet were used because the book of Revelation is in the New Testament, which was originally written in Greek.

This phrase is interpreted by many Christians to mean that Jesus has existed for all eternity or that God is eternal. Many commentators and dictionaries ascribe the title "the alpha and the omega" to both God and to Christ.[6] Barnes' Notes on the New Testament (1974) claims: "It cannot be absolutely certain that the writer meant to refer to the Lord Jesus specifically here ... There is no real incongruity in supposing, also, that the writer here meant to refer to God as such." Most Christian denominations also teach that the title applies to both Jesus and his Father.

The letters Alpha and Omega, in juxtaposition, are often used as a Christian visual symbol (see examples).

Finality (figuratively) - the fact or impression of being an irreversible ending; certainty, decisiveness.

Ending - From a primary word τέλλω tellō (to set out for a definite point or goal); properly the point aimed at as a limit that is (by implication) the conclusion of an act or state (termination [literally figuratively or indefinitely] result [immediate ultimate or prophetic] purpose); specifically an impost or levy (as paid): - + continual custom end (-ing) finally uttermost.
