John 2:13 And the Jews' passover was at hand, and Jesus went up to Jerusalem,
The name passover was given to the feast because the Lord passed over the houses of the Israelites without slaying their firstborn, while the Egyptians were cut off, Ex 12:13. It was celebrated seven days, viz., from the 15th to the 21st of the month ABIB, or NISAN, (April,) Ex 12:15-20.
The passover was a feast instituted in Egypt, to commemorate the destroying angel's passing over the houses of the Israelites, when he slew the firstborn of the Egyptians.
This feast began on the fourteenth day of the first moon, in the first month Nisan, and it lasted only one day; but it was immediately followed by the days of unleavened bread, which were seven, so that the whole lasted eight days, and all the eight days are sometimes called the feast of the passover, and sometimes the feast or days of unleavened bread.
The three most signal benefits vouchsafed to the Israelites were,
1. The deliverance from the slavery of Egypt; to commemorate which they kept the feast of unleavened bread, and the passover.
2. The giving of the law; to commemorate which, they kept the feast of weeks.
3. Their sojourning in the wilderness, and entrance into the promised land; to commemorate which, they kept the feast of tabernacles (ACC)
