'Letting' in the Bible

Moses said, “I am going to leave you, and I will urgently petition (pray, entreat) the Lord that the swarms of insects may leave Pharaoh, his servants, and his people tomorrow; only do not let Pharaoh act deceitfully again by not letting the people go to sacrifice to the Lord.”

Since you are still [arrogantly] exalting yourself [in defiance] against My people by not letting them go,

As for the peoples of the land who bring merchandise or any grain on the Sabbath day to sell, we will not buy from them on the Sabbath or on a holy day; and we will give up raising crops during the seventh year [leaving the land uncultivated], and forgive every debt.

For You, O Lord, are good, and ready to forgive [our sins, sending them away, completely letting them go forever and ever];And abundant in lovingkindness and overflowing in mercy to all those who call upon You.
