God doesn't lie. He fulfilled His promise to Abraham as the following Scripture show.
Joshua 21:43-45
43 And the LORD gave unto Israel all the land which he sware to give unto their fathers; and they possessed it, and dwelt therein.
44 And the LORD gave them rest round about, according to all that he sware unto their fathers: and there stood not a man of all their enemies before them; the LORD delivered all their enemies into their hand.
45 There failed not ought of any good thing which the LORD had spoken unto the house of Israel; all came to pass.
1 Kings 8:56
56 Blessed be the LORD, that hath given rest unto his people Israel, according to all that he promised: there hath not failed one word of all his good promise, which he promised by the hand of Moses his servant.
Nehemiah 9: 7-26
7 Thou art the LORD the God, who didst choose Abram, and broughtest him forth out of Ur of the Chaldees, and gavest him the name of Abraham;
8 And foundest his heart faithful before thee, and madest a covenant with him to give the land of the Canaanites, the Hittites, the Amorites, and the Perizzites, and the Jebusites, and the Girgashites, to give it, I say, to his seed, and hast performed thy words; for thou art righteous:
9 And didst see the affliction of our fathers in Egypt, and heardest their cry by the Red sea;
10 And shewedst signs and wonders upon Pharaoh, and on all his servants, and on all the people of his land: for thou knewest that they dealt proudly against them. So didst thou get thee a name, as it is this day.
11 And thou didst divide the sea before them, so that they went through the midst of the sea on the dry land; and their persecutors thou threwest into the deeps, as a stone into the mighty waters.
12 Moreover thou leddest them in the day by a cloudy pillar; and in the night by a pillar of fire, to give them light in the way wherein they should go.
13 Thou camest down also upon mount Sinai, and spakest with them from heaven, and gavest them right judgments, and true laws, good statutes and commandments:
14 And madest known unto them thy holy sabbath, and commandedst them precepts, statutes, and laws, by the hand of Moses thy servant:
15 And gavest them bread from heaven for their hunger, and broughtest forth water for them out of the rock for their thirst, and promisedst them that they should go in to possess the land which thou hadst sworn to give them.
16 But they and our fathers dealt proudly, and hardened their necks, and hearkened not to thy commandments,
17 And refused to obey, neither were mindful of thy wonders that thou didst among them; but hardened their necks, and in their rebellion appointed a captain to return to their bondage: but thou art a God ready to pardon, gracious and merciful, slow to anger, and of great kindness, and forsookest them not.
18 Yea, when they had made them a molten calf, and said, This is thy God that brought thee up out of Egypt, and had wrought great provocations;
19 Yet thou in thy manifold mercies forsookest them not in the wilderness: the pillar of the cloud departed not from them by day, to lead them in the way; neither the pillar of fire by night, to shew them light, and the way wherein they should go.
20 Thou gavest also thy good spirit to instruct them, and withheldest not thy manna from their mouth, and gavest them water for their thirst.
21 Yea, forty years didst thou sustain them in the wilderness, so that they lacked nothing; their clothes waxed not old, and their feet swelled not.
22 Moreover thou gavest them kingdoms and nations, and didst divide them into corners: so they possessed the land of Sihon, and the land of the king of Heshbon, and the land of Og king of Bashan.
23 Their children also multipliedst thou as the stars of heaven, and broughtest them into the land, concerning which thou hadst promised to their fathers, that they should go in to possess it.
24 So the children went in and possessed the land, and thou subduedst before them the inhabitants of the land, the Canaanites, and gavest them into their hands, with their kings, and the people of the land, that they might do with them as they would.
25 And they took strong cities, and a fat land, and possessed houses full of all goods, wells digged, vineyards, and oliveyards, and fruit trees in abundance: so they did eat, and were filled, and became fat, and delighted themselves in thy great goodness.
26 Nevertheless they were disobedient, and rebelled against thee, and cast thy law behind their backs, and slew thy prophets which testified against them to turn them to thee, and they wrought great provocations.
I hate to say it but some people on this forum have a history of tieing the words God and lie together. They need to contemplate the following Scripture Hebrews 6:18. That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:
