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;

Leviticus 16:29;

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