Exodus 23:14-16 Complete Jewish Bible (CJB)
14 “Three times a year, you are to observe a festival for me. 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.
