'Allowed' in the Bible

The fire on the altar shall be kept burning; it shall not [be allowed to] go out. The priest shall burn wood on it every morning, and he shall arrange the burnt offering on it and offer the fat portions of the peace offerings up in smoke on it.

"As for the person who is afflicted with a skin disease, his garments must be torn and his {hair} must [be allowed to] hang loosely, and he must cover [his] upper lip, and he must call out, 'Unclean! Unclean!'

‘If a fellow countryman of yours becomes so poor he has to sell some of his property, then his nearest relative is to come and buy back (redeem) what his relative has sold.
