On the tenth day of the first month, known as Nisan 10, the children of Israel came up out of Jordan and encamped in Gilgal, on the east border of Jericho, marking a specific time element in their journey. At that time, the Lord instructed Joshua to circumcise the children of Israel again, focusing on those born in the wilderness who had not been circumcised during the forty years of wandering. This act was completed as they prepared for significant observances. Subsequently, on the fourteenth day of the month, they kept the Passover at even in the plains of Jericho, and on the morrow after the Passover, which is the fifteenth, they ate of the old corn of the land, including unleavened cakes and parched corn, on the selfsame day. This observance occurred exactly forty years to the day after leaving Egypt, with the term selfsame indicating an exactly-dated anniversary tied to these pivotal events in their history.

On Abib/Nisan 10, as recorded in Joshua 4:19, the children of Israel crossed the Jordan River and encamped in Gilgal, on the east border of Jericho. This event aligns with a significant timeline of God's faithfulness, paralleling other key moments such as the selection of the Passover lamb in ancient Israel and Christ's triumphant entry into Jerusalem. On this day, in the sequence of Christ's crucifixion, He entered Jerusalem on the back of an ass, symbolizing the choice of the Lamb to be sacrificed. Similarly, the crossing of the Jordan on Abib 10 marks a pivotal moment for Israel as they entered the Promised Land, setting the stage for subsequent events of sanctification and observance as they prepared to inherit the land promised by God.

On the tenth day of Abib, also known as Nisan, every man was to take a lamb for himself, as instructed in Exodus 12:3. This lamb, chosen on Abib/Nisan 10, was to be without blemish, a male of the first year, and kept until the fourteenth day of the same month, when it would be killed at twilight. This selection of the lamb on the tenth day marked the beginning of the preparation for the Passover, symbolizing the setting apart of an innocent and perfect offering, which would later be fulfilled in the life and sacrifice of Jesus Christ on Nisan 14.
