The Prophecy of The Foal of a Colt, has to do with a changing of time to”The Time of The Gentiles” saying;

Behold my servant, whom I uphold; mine Elect, in whom my soul delighteth; I have put My spirit upon Him: He shall bring forth judgment (and justice) to the Gentiles.

And from Zechariah 9.9 ““Rejoice greatly, O daughter of Zion! Shout, O daughter of Jerusalem! Behold, your King is coming to you; He is just and having salvation,(of which they rejected and were condemned til “not one stone was left upon another ” who came Lowly and riding on a donkey, A colt, the foal of a donkey.

Then it became “The Time of The Gentiles” because that is what the colt symbolized with the change of covenants.

That the “Old Covenant that was given to Moses to last up until the coming of Christ who instituted the New Will and Testament” as having to do with the distribution of the deceased mans goods.

For you see that the Old Covenant was a temporary band-aid to hold them over until the Coming of Christ called “The Lamb of God who takes away the Sin of the world” (not just jews), as “The New and Living Way To The Father”. And it was all the rituals associated with the Old Covenant that taught them as “children” a title given to them in the wilderness wanderings nearly 1200 times. By which it anticipated the coming of Christ as the bearer of the New Covenant. That He went to the cross for the sins of all of humanity, whether they accepted the pardon or not. However everyone has to make their own choice to accept…

1.The English words gentle, gentile, and genteel all derive from the Latin gentilis, meaning “of the same family or clan,” which comes from the root of gens (“race, clan or generations”). Gentle (from) Gentile is a later, religious sensel of the Latin word, referring to mean “all the nations” which is SCRIPTIARAL use for the the term Gentiles, and Gentiles means people from ALL Nations.

Except one, the Jews

2.That “Gentiles” means non-Jews, non-Israelites, (Gentiles). More broadly, the term refers to ALL the nations of the world that are NOT Jewish” end quote.

So simply put, Gentile means any nationality but Jew according to the Etymology of the term Gentiles as just displayed. And the message to “All the Nations all started with the fulfillment and expiration with the Jewish Old Covenant promises and prophecy’s explaining how to know when the Old Covenant had become old, and when the New Will and Testament became New, as having to with when the distribution to the Heirs would happen.

We call this Prophecy. And the coming verses from The Old Covenant are these:

Genesis 49. 9.9 And Jacob called unto his sons, and said, Gather yourselves together, that I may tell you that which shall befall you in the last days. (Most people think of last days as meaning a second coming Jesus after a church age. Which would negate this whole prophecy we are now relating from Christ only incarnation in the flesh. But here He continued on and said, “2 Gather yourselves together, and hear, ye (12) sons of Jacob; and hearken unto Israel your father 8 Judah, thou art he whom thy brethren shall praise: thy hand shall be in the neck of thine enemies; thy father’s children shall bow down before thee. 9 Judah is a lion’s whelp: from the prey, my son, thou art gone up: he stooped down, he couched as a lion, and as an old lion; who shall rouse him up? 10 The sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come; and unto him shall the gathering of the people be. 11 Binding his foal unto the vine, and his ass’s colt unto the choice vine; he washed his garments in wine, and his clothes in the blood of grapes:

And again from the Old Covenant with Zechariah of this same prophecy at the end as the last of all the Prophets also saying “9 Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass. 10 And I will cut off the chariot from Ephraim, and the horse from Jerusalem, and the battle bow shall be cut off: and he shall speak peace unto the heathen: and his dominion shall be from sea even to sea, and from the river even to the ends of the earth.

And for the New Will and Testaments fulfillment of those prophecies, we have this from John “12 On the next day many people that were come to the feast, when they heard that Jesus was coming to Jerusalem, 13 Took branches of palm trees, and went forth to meet him, and cried, Hosanna: Blessed is the King of Israel that cometh in the name of the Lord. 14 And Jesus, when he had found a young ass, sat thereon; as it is written, 15 Fear not, daughter of Sion: behold, thy King cometh, sitting on an ass’s colt. 16 These things understood not his disciples at the first: but when Jesus was glorified, then remembered they that these things were written of him, and that they had done these things unto him.
