It is a night to be much observed unto the LORD for bringing them out from the land of Egypt: this is that night of the LORD to be observed of all the children of Israel in their generations.
It is a night to be much observed unto the Lord ... This memorable night of the exodus occurred on the 14th-15th day of the moon, close to the vernal equinox - i:e., either at the end of March or beginning of April. The repetition of the remark in another form in the latter clause of the verse, respecting the impressive and solemn character of that night's transactions, shows the importance of the memorial festival. The initiatory rite of circumcision was indispensable; but that observance being complied with, all Israelites, independently of differences in rank, wealth, or outward estate, were entitled to equal and full participation in the privileges and blessings of the covenant.
