Matthew Poole and continuators on Leviticus 23:27

27 Also on the tenth day of this seventh month, there shall be a day of atonement, it shall be an holy convocation unto you, and ye shall afflict your souls , and offer an offering made by fire unto the LORD.

With fasting, and bitter repentance for all, especially their national sins, among which no doubt▪ God would have them remember their sin of the golden Calf. For as God had threatned to remember it in after times to punish them for it, Exod. 32. 34. so there was great reason why they should remember it to humble themselves for it.
