But he is unchangeable, ¹  and who can change ²  him? Whatever he ³  has desired, he does.

In the same way ¹  God wanted to demonstrate more clearly to the heirs of the promise that his purpose was unchangeable, ²  and so he intervened with an oath,

so that we who have found refuge in him ¹  may find strong encouragement to hold fast to the hope set before us through two unchangeable things, since it is impossible for God to lie.
