'Observe' in the Bible

To this very day they observe their earlier practices. They do not worship the Lord; they do not obey the rules, regulations, law, and commandments that the Lord gave the descendants of Jacob, whom he renamed Israel.

But they pay no attention; instead they observe their earlier practices.

Pay attention, Lord, and hear! Open your eyes, Lord, and observe! Listen to the message Sennacherib sent and how he taunts the living God!

The king ordered all the people, "Observe the Passover of the Lord your God, as prescribed in this scroll of the covenant."
