Leviticus 23:32

“It [shall be] unto you a sabbath of rest, etc.] (See Gill on “<031631>Leviticus 16:31”); and this is thought by some f830 to be the sabbath spoken of in (<235813>Isaiah 58:13); and ye shall afflict your souls; in the ninth [day] of the month at even; the fast was to begin at the close of the ninth day, and to continue to the end of the tenth; so Maimonides f831: he begins to fast and afflict himself at the evening of the ninth next to the tenth; and so at the going out of it he continues in his affliction a little while of the night of the eleventh, next to the tenth, which is confirmed by what follows: from even unto even shall ye celebrate your sabbath; which some understand of the sabbath…”

“From even to even - The day of atonement began at the evening of the ninth day, and continued till the evening of the tenth day. Ye shall celebrate your sabbath - This particular sabbath is called your sabbath, possibly to note the difference between this and other sabbaths: for the weekly sabbath is oft called the sabbath of the Lord. The Jews are supposed to begin every day, and consequently their sabbaths, at the evening, in remembrance of the creation, as Christians generally begin their days and sabbaths with the morning in memory of Christ's resurrection. Leviticus 23:34”

“a sabbath: Lev 16:31; Mat 11:28-30; Heb 4:3, Heb 4:11 afflict: Lev 23:27; Psa 35:13, Psa 51:17, Psa 69:10, Psa 69:11, Psa 126:5, Psa 126:6; Isa 57:15, Isa 57:18, Isa 57:19, Isa 58:3-7; Isa 61:3; Mat 5:4; Co1 11:31 celebrate your sabbath: Heb. rest Leviticus 23:34”

“"Ye shall rest your rest," i.e., observe the rest that is binding upon you from all laborious work. Leviticus 23:33”
