'Festival' in the Bible

At length, on the day of the Harvest Festival, they had all met in one place;

When he saw how this was agreeable to the Jews, he proceeded to arrest Peter, too. This happened during the Festival of Unleavened Bread.

After the Festival of Unleavened Bread, we sailed from Philippi, and days later we joined them in Troas and stayed there for seven days.

For Paul's plan was to sail past Ephesus, so as not to spend much time in the province of Asia; since he was very desirous of being in Jerusalem, if possible, on the day of the Harvest Festival.
