Matthew Poole and continuators on Exodus 12:8

8 And they shall eat the [illegible: 1+ letters]lesh in that night, rost with fire, and unleavened bread, and with bitter herbs they shall eat it.

(i. e.) The night following the fourteenth, and beginning the fifteenth, day. The lamb was killed upon the 14th. day, in the evening or close thereof, but it was eaten upon the 15th. day, to wit in the beginning of it: whence the Passeover is said to be offered sometimes upon the 14th. and sometimes upon the 15th. day, which may serve for▪ the reconciliation of some seemingly contrary Scriptures.

Partly for expedition, ver. 11. and principally to be a type of the lamb of God Christ and of the sharp and dreadful pains which he suffered not onely from men, but from God too, and from the fire of his sore displeasure against sinners, whose place and person Christ sustained in his sufferings.

Partly as a Monument of their speedy departure out of Egypt, which gave them not time to leaven their bread, ver. 34. which is the reason alledged for it, Deut. 16. 3. partly to teach us how men should be qualified that come to the Sacrament, they should be purged from error, and pride, and malice, and hypocrisie, which are called and compared to leaven, Mat. 16. 6, 11. Luk. 12. 1. 1 Cor. 5. 8. and partly to signifie the singular purity of Christ from all kinds of spiritual leaven▪

Both to remind them of their hard service and bitter usage in Egypt, Exod. 1. 14. from which God delivered them, Deut. 16. 3. and to prefigure the further crosses and troubles which they were to expect between their going out of Egypt and coming to Canaan. Or, with bitternesses, i. e. with great bitterness, or with grief of heart, that together with faith in God and in Christ and hope and joy for their approaching deliverance they might exercise bitter and hearty repentance for their Idolatries and other sinful practises whereof they were guilty in Egypt. And this instructs us as well as them of the absolute necessity of true and bitter repentance in all those that would profitably [illegible: 1+ letters]eed upon Christ our passeover.
