Numbers 23:19

nor a human being, that he should change his mind.

Has he said, and will he not do it?

Or has he spoken, and will he not make it happen?

John 17:17

17:17 Set them apart in the truth; your word is truth.

Titus 1:2

1:2 in hope of eternal life, which God, who does not lie, promised before the ages began.
