Deuteronomy 26:1 Meaning and Commentary

Deuteronomy 26:1

And it shall be, when thou [art] come in unto the land
The land of Canaan, which they were now on the borders of, and just entering into:

which the Lord thy God giveth thee [for] an inheritance;
which is often mentioned, to observe that it was not through their merits, but his gift, that they should enjoy the land; and the rather here to enforce the following law concerning the basket of firstfruits:

and possessest it, and dwellest therein;
not only had entered into it, but got the possession of it, and settled there. This shows as Jarchi observes, that they were not bound to the firstfruits till they had subdued the land and divided it; not as soon as they were in it.

Deuteronomy 26:1 In-Context

1 And it shall be when thou shalt have entered into the land, which the Lord thy God gives thee to inherit it, and thou shalt have inherited it, and thou shalt have dwelt upon it,
2 that thou shalt take of the first of the fruits of thy land, which the Lord thy God gives thee, and thou shalt put them into a basket, and thou shalt go to the place which the Lord thy God shall choose to have his name called there.
3 And thou shalt come to the priest who shall be in those days, and thou shalt say to him, I testify this day to the Lord my God, that I am come into the land which the Lord sware to our fathers to give to us.
4 And the priest shall take the basket out of thine hands, and shall set it before the altar of the Lord thy God:
5 and he shall answer and say before the Lord thy God, My father abandoned Syria, and went down into Egypt, and sojourned there with a small number, and became there a mighty nation and a great multitude.
