Exodus 23:14-16

CLV(i) 14 Three times shall you celebrate to Me in the year: 15 you shall observe the celebration of unleavened cakes; seven days shall you eat unleavened cakes, just as I instructed you, at the appointed time in the month Aviv, for in it you went forth from Egypt, and none shall appear before Me empty-handed. 16 also observe the celebration of the harvest of the firstfruits of your yields from what you are sowing in the field: and observe the celebration of ingathering at the going forth of the year, when you gather your yields from the field.
