'Observe' in the Bible

He ordered Judah to seek the Lord God of their ancestors and to observe his law and commands.

Jehoshaphat was afraid, so he decided to seek the Lord's advice. He decreed that all Judah should observe a fast.

Hezekiah sent messages throughout Israel and Judah; he even wrote letters to Ephraim and Manasseh, summoning them to come to the Lord's temple in Jerusalem and observe a Passover celebration for the Lord God of Israel.

The king, his officials, and the entire assembly in Jerusalem decided to observe the Passover in the second month.

They were unable to observe it at the regular time because not enough priests had consecrated themselves and the people had not assembled in Jerusalem.

So they sent an edict throughout Israel from Beer Sheba to Dan, summoning the people to come and observe a Passover for the Lord God of Israel in Jerusalem, for they had not observed it on a nationwide scale as prescribed in the law.

A huge crowd assembled in Jerusalem to observe the Feast of Unleavened Bread in the second month.
