Exodus 12:24 Meaning and Commentary

Exodus 12:24

And ye shall observe this thing for an ordinance to thee and
thy sons for ever.

Exodus 12:24 In-Context

22 and dip ye a bundle of hyssop, in the blood which is in the threshold, either in a vessel beside the threshold, and sprinkle ye thereof on the lintel, and ever either (door-)post; none of you shall go out at the door of his house till the morrowtide. (and dip ye a bundle of hyssop in the blood which is on the threshold, or in a vessel beside the threshold, and sprinkle some of it on the lintel, and on both door-posts; and then none of you shall go out of the door of his house until the morning.)

23 For the Lord shall pass [forth] smiting the Egyptians; and when he shall see the blood in the lintel, and in ever either post (and when he shall see the blood on the lintel, and on both door-posts), he shall pass (over) the door of the house; and he shall not suffer the smiter to enter into your houses, and to hurt you.

24 Keep thou this word; it shall be a lawful thing to thee and to thy sons till into without end. (Do thou this thing; yea, it shall be an everlasting rite for thee and for thy sons.)

25 And when ye shall enter into the land which the Lord shall give to you, as he promised, ye shall keep these ceremonies;

26 and when your sons shall say to you, What is this religion? (What is the meaning of this rite?)
