'Requirement' in the Bible

Even when the cloud stayed over the tabernacle many days, the Israelites carried out the Lord’s requirement and did not set out.

They camped at the Lord’s command, and they set out at the Lord’s command. They carried out the Lord’s requirement according to His command through Moses.

A clean man will gather the ashes of the heifer, and he will put [them] in a clean {place outside the camp}; it will be for the community of the {Israelites} as a requirement for waters of impurity; it [is] a purification [offering].

and if his father has no brothers, then you are to give his inheritance to his relative nearest to him from his family, and he will possess it. This will be for the Israelites a legal requirement, as the Lord commanded Moses.'"
