[19] "Different seeds": This law tends to recommend simplicity and plain dealing in all things, and to teach the people not to join any false worship or heresy with the worship of the true God.
[23] "Firstfruits": Proeputia, literally, their foreskins; it alludes to circumcision, and signifies that for the first three years the trees were to be as uncircumcised, and their fruit unclean: till in the fourth year their increase was sanctified and given to the Lord, that is, to the priests.
