'Observe' in the Bible

Carefully observe the commands of the Lord your God, the decrees and statutes He has commanded you.

For if you carefully observe every one of these commands I am giving you to follow—to love the Lord your God, walk in all His ways, and remain faithful to Him—

“Observe the month of Abib and celebrate the Passover to the Lord your God, because the Lord your God brought you out of Egypt by night in the month of Abib.

It is to remain with him, and he is to read from it all the days of his life, so that he may learn to fear the Lord his God, to observe all the words of this instruction, and to do these statutes.

Therefore, observe the words of this covenant and follow them, so that you will succeed in everything you do.
