Hebrews 6:16-18

New International Version

¹⁶ People swear by someone greater than themselves, and the oath confirms what is said and puts an end to all argument.^{(A) 17} Because God wanted to make the unchanging^(B) nature of his purpose very clear to the heirs of what was promised,^(C) he confirmed it with an oath. ¹⁸ God did this so that, by two unchangeable things in which it is impossible for God to lie,^(D) we who have fled to take hold of the hope^(E) set before us may be greatly encouraged.
