'Observed' in the Bible

So Solomon and all Israel with him—a very great assembly, from the entrance to Hamath to the Brook of Egypt—observed the festival at that time for seven days.

When the queen of Sheba observed Solomon’s wisdom, the palace he had built,

so they affirmed the proposal and spread the message throughout all Israel, from Beer-sheba to Dan, to come to observe the Passover of Yahweh, the God of Israel in Jerusalem, for they hadn’t observed it often, as prescribed.

The Israelites who were present in Jerusalem observed the Festival of Unleavened Bread seven days with great joy, and the Levites and the priests praised the Lord day after day with loud instruments.

The whole congregation decided to observe seven more days, so they observed seven days with joy,

Josiah observed the Lord’s Passover and slaughtered the Passover lambs on the fourteenth day of the first month.

The Israelites who were present in Judah also observed the Passover at that time and the Festival of Unleavened Bread for seven days.

No Passover had been observed like it in Israel since the days of Samuel the prophet. None of the kings of Israel ever observed a Passover like the one that Josiah observed with the priests, the Levites, all Judah, the Israelites who were present in Judah, and the inhabitants of Jerusalem.

In the eighteenth year of Josiah’s reign, this Passover was observed.
