The simple answer to your question is NO.
God was asking Abraham to walk towards an earth that he would show him where God's Everlasting Kingdom would be established, a kingdom where Righteousness abounds. God's undertaking of showing Abraham and his descendants an earth was a distant future event that will be five ages in the making.
The "Promised Land" of Gen_15:17ff was meant to be confirmation for the Descendants of Abraham that they too would inherit the earth as promised in Gen_12:7. Around 680 years after the Gen_13:14-17 was given the descendants of Abraham gained possession of the "Promised Land" and it was not until the time of Solomon that they had gained possession of all of the "Promised Land" and that this possession of the Promised land would only be for a period of around 1450 years before God would cause the descendant to be scattered to the four corner of the earth because of their iniquities.
Shalom
You asked the question though of
Jesus, said in Matt_5:5 Blessed are the meek, for they shall inherit the earth.
Why did Jesus say “earth” when Genesis says “land” ...there is no conflict there, but “fullness” of the promise from “land” to “All”. When God said He makes all things New where righteousness dwells...again this is the promise made flourishing. Those born of God are new creatures belonging to the New creation...the children of Promise. Paul spoke of not all are Israel but those born of the promise...Inheriting all the promises spoken to Abraham. The New Testament says Jesus confirmed those promises made to Abraham. You can’t reduce it to past; they were scattered for a reason. Isaiah 45:17-18 But Israel shall be saved in the Lord
with an everlasting salvation: ye shall not be ashamed nor confounded world without end. [18] For thus saith the Lord that created the heavens;
God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the Lord ; and there is none else.
^ tells a lot in God formed and made the earth ...established it...He made it not “in vain” meaning He did not make it to be emptiness or void or without profit. But as His words do not return “void” but with Spirit ...also the earth He created not in vain...but with Spirit. Who are the Sons of God...those meek and lowly as Jesus said “learn of Me for I am meek and lowly of heart.” Romans 8:20-21 For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope, [21]
Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
^out of the bondage shall the creation be delivered unto those Born of God. Those are the “promised children” of Abraham.
Daniel 2:19-21 Then was the secret revealed unto Daniel in a night vision. Then Daniel blessed the God of heaven. [20] Daniel answered and said, Blessed be the name of God for ever and ever: for wisdom and might are his: [21] And he changeth the times and the seasons:
he removeth kings, and setteth up kings: he giveth wisdom unto the wise, and knowledge to them that know understanding:
^He removes kings, and sets up kings (His children)...as seen in Revelation pulling down kings and setting others in their place. Daniel 7:22
Until the Ancient of days came, and
judgment was given to the saints of the most High; and
the time came that the saints possessed the kingdom.
Daniel 7:27 And the kingdom and dominion, and the greatness of the kingdom under the whole heaven,
shall be given to the people of the saints of the most High, whose kingdom is
an everlasting kingdom, and all dominions shall serve and obey him.
Ephesians 1:21-23 Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come: [22] And hath put all things under his feet, and gave him to be the head over all things to the church, [23] Which
is his body, the fulness of him that filleth all in all.
Isaiah 10:22-23 For
though thy people Israel be as the sand of the sea,
yet a remnant of them shall return: the
consumption decreed shall overflow with righteousness. [23] For the Lord God of hosts shall make a consumption, even
determined,
in the midst of all the land.
“...the consumption (wasting) shall overflow with righteousness.” His. Isaiah 28:22 Now therefore be ye not mockers, lest your bands be made strong: for I have heard from the Lord God of hosts
a consumption, even determined
upon the whole earth.
“Behold, I make all things New.” No mistaken...He IS the Land. Isaiah 60:3-4 And the Gentiles shall come to
thy light, and
kings to the brightness of thy rising. [4] Lift up thine eyes round about, and see: all they gather themselves together, they come to thee: thy sons shall come from far, and thy daughters
shall be nursed at thy side.
