'Humility' in the Bible

“Also the tenth day of this seventh month is the Day of Atonement; it shall be a holy convocation for you, and you shall humble yourselves [by fasting] and present an offering by fire to the Lord.

If there is any person who will not humble himself on this same day, he shall be cut off from his people [excluding him from the atonement made for them].

It is to be to you a Sabbath of complete rest, and you shall humble yourselves. On the ninth day of the month at evening, from evening to evening you shall keep your Sabbath.”
