'Sing' in the Bible

Then, when many evils and troubles will have come upon them, this song will serve as a witness against them, since their descendants won't fail to sing it. I know the plan that they are devising even before I bring them into the land that I promised them by an oath."

"Sing for joy, nations! Sing for joy, people who belong to him! For he'll avenge the blood of his servants, turn on his adversary, and cleanse both his land and his people."
