'Celebrate' in the Bible

Then they said to one another, "It's not right what we're doing! This is a day to celebrate, but we haven't told anyone. If we wait until dawn, we'll be punished. So come on, let's go and inform the royal palace."

After this, the king commanded all of the people, "Celebrate the Passover to the LORD your God, just as it's prescribed in this Book of the Covenant."
