Numbers 23:19

God is not a man, that he should lie
Man is a creature consisting of a body of flesh and blood, and of a soul, a created and finite spirit; but God, though he has the parts of an human body ascribed to him in a figurative sense, yet is not to be conceived of in a corporeal manner; and though he is a Spirit, yet eternal, immense, and infinite; and much less is as a sinful man, who goes astray from the womb speaking lies; no, let God be true, and every man a liar: he is God, that cannot lie; his counsels of old are faithfulness and truth; his promises yea and amen in Christ; the Scriptures inspired by him are true, and the prophecies of them are punctually accomplished, particularly what he foretold of the people of Israel, and promised unto them; that they should be happy, and inherit the land of Canaan; that be would be true and faithful to them, and there could be no hope, by any means whatever, to make him false and unfaithful to his word: neither the son of man, that he should repent; repentance is found in men, who repent for what they have done, or change their minds, as to what they intended to do or set about; perceiving it to be wrong to do it, or that they are able to do it, some unforeseen thing turning up they were not aware of: but nothing of this kind belongs to God, or can befall him; he never changes his mind, alters his counsels, purposes, and decrees, and never varies in his affections to his people, nor makes void his choice of them, or covenant with them; and his calling of them by his grace, and his gifts of grace bestowed upon them, are without repentance: and particularly with respect to the people of Israel, there was no reason to hope or believe that God would change his purposes or promises respecting their outward happiness, and enjoyment of the land of Canaan; or that ever he would be prevailed upon to curse them, or admit them to be cursed, when he was determined, and had so peremptorily promised that he would bless them:

hath he said, and shall he not do it?
or "hath he spoken, and shall he not make it good?" whether it be with regard to things temporal, spiritual, or eternal; for there is no variableness nor shadow of turning in his mind; he never forgets his word, he foresees all events, he is able to perform, and is true and faithful; and therefore whatever is gone out of his lips will never be altered, but will be most certainly fulfilled, ( Psalms 89:34 ) ( Isaiah 14:24 Isaiah 14:27 ) .
