| Gill's Exposition of the Entire Bible Thus did all the children of Israel,.... They slew a lamb, and roasted and ate it, with unleavened bread, and bitter herbs, and took a bunch of hyssop, and dipped it in the blood, and struck the lintel and the side posts of the doors of their houses: this they did on the night of their deliverance out of Egypt: as the Lord commanded Moses and Aaron, so did they; being instructed by them; which is an instance of their ready and cheerful obedience to the divine will, which they were under great obligation to perform, from a grateful sense of the wonderful mercy and favour they now were made partakers of.
Keil and Delitzsch Biblical Commentary on the Old TestamentExodus 12:50 closes the instructions concerning the Passover with the statement that the Israelites carried them out, viz., in after times (e.g., Numbers 9:5); and in Exodus 12:51 the account of the exodus from Egypt is also brought to a close. All that Jehovah promised to Moses in Exodus 6:6 and Exodus 6:26 had now been fulfilled. But although v. 51 is a concluding formula, and so belongs to the account just closed, Abenezra was so far right in wishing to connect this verse with the commencement of the following chapter, that such concluding formulae generally serve to link together the different incidents, and therefore not only wind up what goes before, but introduce what has yet to come.

Matthew Henry's Concise Commentary12:43-51 In times to come, all the congregation of Israel must keep the passover. All that share in God's mercies should join in thankful praises for them. The New Testament passover, the Lord's supper, ought not to be neglected by any. Strangers, if circumcised, might eat of the passover. Here is an early indication of favour to the gentiles. This taught the Jews that their being a nation favoured by God, entitled them to their privileges, not their descent from Abraham. Christ our passover is sacrificed for us, 1Co 5:7; his blood is the only ransom for our souls; without the shedding of it there is no remission; without the sprinkling of it there can be no salvation. Have we, by faith in him, sheltered our souls from deserved vengeance under the protection of his atoning blood? Do we keep close to him, constantly depending upon him? Do we so profess our faith in the Redeemer, and our obligations to him, that all who pass by may know to whom we belong? Do we stand prepared for his service, ready to walk in his ways, and to separate ourselves from his enemies? These are questions of vast importance to the soul; may the Lord direct our consciences honestly to answer them.
Matthew Henry's Whole Bible CommentaryVerses 43-51 Some further precepts are here given concerning the passover, as it should be observed in times to come. I. All the congregation of Israel must keep it, v. 47. All that share in God's mercies should join in thankful praises for them. Though it was observed in families apart, yet it is looked upon as the act of the whole congregation; for the smaller communities constituted the greater. The New-Testament passover, the Lord's supper, ought not to be neglected by any who are capable of celebrating it. He is unworthy the name of an Israelite that can contentedly neglect the commemoration of so great a deliverance. 1. No stranger that was uncircumcised might be admitted to eat of it, v. 43, 45, 48. None might sit at the table but those that came in by the door; nor may any now approach to the improving ordinance of the Lord's supper who have not first submitted to the initiating ordinance of baptism. We must be born again by the word ere we can be nourished by it. Nor shall any partake of the benefit of Christ's sacrifice, or feast upon it, who are not first circumcised in heart, Col. 2:11. 2. Any stranger that was circumcised might be welcome to eat of the passover, even servants, v. 44. If, by circumcision, they would make themselves debtors to the law in its burdens, they were welcome to share in the joy of its solemn feasts, and not otherwise. Only it is intimated (v. 48) that those who were masters of families must not only be circumcised themselves, but have all their males circumcised too. If in sincerity, and with that zeal which the thing required and deserves, we give up ourselves to God, we shall, with ourselves, give up all we have to him, and do our utmost that all ours may be his too. Here is an early indication of favour to the poor Gentiles, that the stranger, if circumcised, stands upon the same level with the home-born Israelite. One law for both, v. 49. This was a mortification to the Jews, and taught them that it was their dedication to God, not their descent from Abraham, that entitled them to their privileges. A sincere proselyte was as welcome to the passover as a native Israelite, Isa. 56:6, 7. II. In one house shall it be eaten (v. 46), for good-fellowship sake, that they might rejoice together, and edify one another in the eating of it. None of it must be carried to another place, nor left to another time; for God would not have them so taken up with care about their departure as to be indisposed to take the comfort of it, but to leave Egypt, and enter upon a wilderness, with cheerfulness, and, in token of that, to eat a good hearty meal. The papists' carrying their consecrated host from house to house is not only superstitious in itself, but contrary to this typical law of the passover, which directed that no part of the lamb should be carried abroad. The chapter concludes with a repetition of the whole matter, that the children of Israel did as they were bidden, and God did for them as he promised (v. 50, 51); for he will certainly be the author of salvation to those that obey him. |
