The Lord specified when He wanted Israel to observe the all-important Day of Atonement,
“On the tenth day of this seventh month you shall have a holy convocation. You shall afflict your souls; you shall not do any work” (Numbers 29.7).
Seven months after leaving Egypt, they would afflict their souls (usually with fasting), refrain from work, and have this holy convocation.
For you see, although God loved His people Israel, they were sinners, and needed to remember their sins, and that God is the only one who can forgive us of our sins.
