This verse in the King James

King James wording
Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.

The one who gives the teaching’s charge remains with you through the completion of the age.

The teaching takes form as you keep what is entrusted to you. The one who gives the charge is with you through the completion of the age, holding the sending and the presence together.

WHAT THIS UNDOES

The verse dissolves the belief that being commissioned means being left to carry the work alone: the command comes with the promise of continuing presence.

τηρεῖν

tērein

GROWS FROM

τηρ-

tēr-

To keep watch over, guard, or preserve.

The verb behind “observe” is ⁨τηρεῖν⁩ (tērein), from ⁨τηρέω⁩ (tēreō, to keep or guard). Its compounds show keeping as an active custody: the teaching is preserved as it is carried into life, not merely noticed or remembered.

ALSO GROWS

diatēreō: To keep carefully or preserve.

διατηρέω

In Luke 2:51, this verb describes Mary keeping the sayings in her heart, showing how teaching can be held and carried forward.

syntēreō: To keep, guard, or preserve.

συντηρέω

This compound also carries the sense of protective keeping, illuminating “observe” as guarding the teaching through lived practice.

αἰῶνος

aiōnos

GROWS FROM

αἰών

aiōn

An age, era, or span of time.

The Greek phrase behind “the end of the world” speaks of the completion of an age. This adds a time-shaped horizon to the promise: the presence continues through the age’s completion.

ALSO GROWS

aiōnios: Age-related; belonging to or lasting through an age.

αἰώνιος

This adjective grows from the same word for age, giving expressions such as “life eternal” an age-shaped depth.

aiōnes: Ages; spans of time.

αἰῶνες

The plural form evokes ages as successive spans, widening the horizon of the promise beyond a single moment.

The presence that sends a person remains with them through the whole span of the work.

And behold, I am with you, and I will guard you in every place you go, and I will bring you back into this land; for I will not leave you until I have done the word I have spoken to you.
Genesis 28:15 · SDVPresence accompanies the journey and holds it until the spoken purpose is complete.
Did I not command you? Hold fast and be firm. Do not tremble, and do not be shattered, for the LORD your God is with you wherever you go.
Joshua 1:9 · SDVThe command and the assurance of presence arrive together wherever the journey leads.
Let your way of living be without the love of silver, and let what is at hand be enough, for he has said, I will never let go of you, nor leave you behind.
Hebrews 13:5 · SDVThe promise of not being left extends through the reader’s present life.
And I will ask the Father, and he will give you another one who comes alongside, that he may be with you for the ages.
John 14:16 · SDV

Both verses use ⁨αἰών⁩ (aiōn, age) for the time horizon: Matthew speaks of the age’s completion, while John says the Comforter abides with you for ever. The shared word links Jesus’ promise of presence with the promise of an abiding presence.
