Exodus 23:15-17 Complete Jewish Bible (CJB)
15 Keep the festival of matzah: for seven days, as I ordered you, you are to eat matzah at the time determined in the month of Aviv; for it was in that month that you left Egypt. No one is to appear before me empty-handed. 16 Next, the festival of harvest, the firstfruits of your efforts sowing in the field; and last, the festival of ingathering, at the end of the year, when you gather in from the fields the results of your efforts. 17 Three times a year all your men are to appear before the Lord, Adonai.
