Exodus 23:15-17 Expanded Bible (EXB)
15 You must celebrate the ·Feast [Festival] of Unleavened Bread [34:18] in the way I commanded you. For seven days you must eat ·bread that is made without yeast [unleavened bread] at the set time during the month of Abib [13:4], the month when you came out of Egypt. No one is to ·come to worship [appear before] me ·without bringing an offering [empty-handed].
16 “You must celebrate the ·Feast [Festival] of Harvest [C called Feast of Weeks in 34:22; later called Pentecost]. Offer to God the first things you harvest from the crops you planted in your fields.
“You must celebrate the ·Feast [Festival] of Ingathering [C later called Feast of Shelters or Booths; Lev. 23:33–36] in the fall, when you gather all the crops from your fields.
17 “So three times during every year all your males must come ·to worship [L before] the Lord God.
