'Vow' in the Bible

They also made a vow to the LORD with loud voices, shouting, trumpets, and horns.

Everybody in Judah was very glad to make their oath, because they had made their vow with all their heart and had sought him with all of their might, and they found him! The LORD also gave them rest in their surrounding lands.

He also rebelled against King Nebuchadnezzar, who had made him vow allegiance in the name of God. He was stubborn and obstinate, and refused to return to the Lord God of Israel.
