'Afflict Your Souls' in the Bible

And it shall be a statute forever to you: in the seventh month, on the tenth of the month, you shall afflict your souls and do no work at all, the native and the alien who is staying among you.

It shall be a sabbath of rest to you, and you shall afflict your souls, by a statute forever.

Also, on the tenth of this seventh month, this is a day of atonement. It shall be a holy convocation to you. And you shall afflict your souls and offer a fire offering to Jehovah.
