'Unleavened' in the Bible

He followed the daily requirement for offerings according to the commandment of Moses for Sabbaths, New Moons, and the three annual appointed festivals: the Festival of Unleavened Bread, the Festival of Weeks, and the Festival of Booths.

A very large assembly of people was gathered in Jerusalem to observe the Festival of Unleavened Bread in the second month.

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