'Vowed' in the Bible

And known hath been Jehovah to Egypt, And the Egyptians have known Jehovah in that day, And done sacrifice and present, And vowed a vow to Jehovah, and completed it.

"As far as I am concerned, this is like in Noah's time, when I vowed that the waters of Noah's flood would never again cover the earth. In the same way I have vowed that I will not be angry at you or shout at you.
