'Watch' in the Bible

Didn’t the one God make us with a remnant of His life-breath? And what does the One seek? A godly offspring. So watch yourselves carefully, and do not act treacherously against the wife of your youth.

“If he hates and divorces his wife,” says the Lord God of Israel, “he covers his garment with injustice,” says the Lord of Hosts. Therefore, watch yourselves carefully, and do not act treacherously.

"Watch out! I'm sending my messenger, and he will prepare the way before me. Then suddenly, the LORD you are looking for will come to his Temple. He is the messenger of the covenant whom you desire. Watch out! He is coming!" says the LORD of the Heavenly Armies.
