'Observe' in the Bible

They are still practicing the former customs to this day. None of them fear the Lord or observe their statutes and ordinances, the law and commandments the Lord commanded the descendants of Jacob. He had renamed him Israel.

And the statutes, and the ordinances, and the law, and the commandment, which he wrote for you, ye shall observe to do for evermore; and ye shall not fear other gods.

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

Turn your ear, LORD, and listen! Open your eyes, LORD, and observe! Listen to the message sent by Sennacherib to insult the living God!

Neither will I make the feet of Israel move any more out of the land which I gave their fathers; only if they will observe to do according to all that I have commanded them, and according to all the law that my servant Moses commanded them.

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