Numbers 23:19

¹⁷ So he returned to Balak, who was standing there by his burnt offering with the princes of Moab. “What did the LORD say?” Balak asked.

God is not a man, that He should lie, or a son of man, that He should change His mind. Does He speak and not act? Does He promise and not fulfill?

²⁰ I have indeed received a command to bless; He has blessed, and I cannot change it.

²¹ He considers no disaster for Jacob; He sees no trouble for Israel. The LORD their God is with them, and the shout of the King is among them.

Do read the surrounding verses too, because the context often says more than a single verse.
