TSK · Exodus 13:4

And in the fourth generation they shall come hither again: for the iniquity of the Amorite is not yet full.

This month shall be unto you the beginning of months: it shall be the first month of the year to you.

The feast of unleavened bread shalt thou keep. Seven days thou shalt eat unleavened bread, as I commanded thee, at the time appointed in the month Abib; for in the month Abib thou camest out from Egypt.
