'Humble Yourselves' in the Bible

"This is to be a perpetual statute for you: On the tenth day of the seventh month, you (including both the native born and the resident alien) are to humble yourselves by not doing any work,

It's the Sabbath of all Sabbaths for you, so humble yourselves. This is to be a perpetual statute.

"However, on the tenth day of this seventh month is the Day of Atonement. It's a sacred assembly for you. Humble yourselves and bring an offering made by fire to the LORD.

It's a Sabbath of rest for you on which you are to humble yourselves starting the evening of the ninth day of the month. You are to observe your Sabbath from evening to evening."
