Leviticus 16:29BSB·traditional attribution

This is to be a permanent statute for you: On the tenth day of the seventh month, you shall humble yourselves and not do any work—whether the native or the foreigner who resides among you—

29. And this shall be a statute for ever. This day of public atonement is now finally mentioned in express terms, and the affliction of souls, of which fuller notice is taken in chap. 23, is touched upon, that they may more diligently exercise themselves in more serious penitential meditations, nor doubt that they are truly purged before God; and yet in a sacramental manner...

Matthew Henry Presbyterian @wholebiblehenry

I. We have here some additional directions in reference to this great solemnity, particularly, 1. The day appointed for this solemnity. It must be observed yearly on the tenth day of the seventh month, Lev 16:29. The seventh had been reckoned the first month, till God appointed that the month in which the children of Israel came out of Egypt should thenceforward be accounted and called the first month.

For on that day shall the priest make an atonement for you to cleanse you,.... By offering the sin offering for them; typical of the sacrifice of Christ, whose soul was made an offering for sin whereby atonement is made for it, and whose blood cleanses from all sin.
