Leviticus 23:27

Also on the tenth day of this seventh month ,.... Tisri, the same as before, answering to part of our September, and part of October:

there shall be a day of atonement ; for all the sins of the year past; see Leviticus 16:29 ,

it shall be an holy convocation unto you : when they should be called together for the exercise of holy duties:

and ye shall afflict your souls ; their souls, by repentance, contrition, and humiliation for sin, and their bodies by fasting; and, as the Targum of Jonathan paraphrases it,"by abstaining from eating and drinking, and the advantage of bathing and wiping, and the use of the bed and sandals;'hence called the fast, Acts 27:9 ; See Gill on Leviticus 16:29 ,

and offer an offering made by fire unto the Lord ; a burnt offering, of which see Numbers 29:8 .
