John Lightfoot on Matthew 23:23

[Ye pay tithe of mint.] I. "This is the general rule about tithes; whatsoever serves for food, whatsoever is kept [that is, which is not of common right], and whatsoever grows out of the earth, shall be tithed."

II. According to the law, cattle, corn, and fruit were to be tithed: the way and measure of which, as the scribes teach, was this: "Of bread-corn that is thrashed and winnowed, 1. A fifth part is taken out for the priest; this was called the great offering. 2. A tenth part of the remainer belong to the Levite; this was called the first tenth, or tithe. 3. A tenth part again was to be taken out of the remainder, and was to be eaten at Jerusalem, or else redeemed; this was called the second tithe. 4. The Levite gives a tenth part out of his to the priest; this was called the tithe of the tithe." These are handled at large in Peah, Demai, Maaseroth, &c.

III. The tithing of herbs is from the Rabbins. This tithing was added by the scribes, and yet approved of by our Saviour, when he saith, "Ye ought not to have left these undone." Hear this, O thou who opposest tithes. The tithing of herbs was only of ecclesiastical institution, and yet it hath the authority of our Saviour to confirm it, "Ye ought not to have left these things undone": and that partly on account of the justice of the thing itself, and the agreeableness of it to law and reason, partly that it was commanded by the council sitting in Moses' chair, as it is, verse 2.

IV. [Mint.] ...is reckoned among those things which come under the law of the seventh year. Where Rambam saith, "In the Aruch it is minta." It is called sometimes mintha: where R. Solomon writes, "In the Aruch it is minta in the mother tongue, and it hath a sweet smell; therefore they strew it in synagogues for the sake of its scent."

[Anise.] ...R. Solomon, "anise is a kind of herb, and is tithed, both as to the seed and herb itself." Rambam writes thus: "It is eaten raw after meat, and is not to be boiled; while, therefore, it is not boiled, it comes under the law of tithing." The Gloss "in the Roman language is anethum [anise], and is tithed, whether it be gathered green or ripe."

[Cummin.] ...It is reckoned among things that are to be tithed.
