'Flocking' in the Bible

The Lord asked, "How can I leave you unpunished, Jerusalem? Your people have rejected me and have worshiped gods that are not gods at all. Even though I supplied all their needs, they were like an unfaithful wife to me. They went flocking to the houses of prostitutes.

I will throw my bird net over them while they are flying, I will bring them down like birds in the sky; I will discipline them when I hear them flocking together.
