Leviticus 23:32

It shall be to you a Sabbath of solemn rest , and you shall afflict yourselves . On the ninth day of the month beginning at evening , from evening to evening shall you keep your Sabbath .

It is a day of sabbath rest for you, and you must deny yourselves. From the evening of the ninth day of the month until the following evening you are to observe your sabbath.”

It shall be unto you a sabbath of rest, and ye shall afflict your souls : in the ninth day of the month at even, from even unto even, shall ye celebrate your sabbath.
