'Regarding' in the Bible

"Here's what the descendants of Kohath are to do regarding the Tent of Meeting and what's inside the Most Holy Place:

When a man becomes under the control of an attitude of jealousy regarding his wife, he is to present her to the Lord, and the priest is to apply this entire statute to her.

"Now regarding a descendant of Levi who is 25 years and above, he is to enter work in the service at the appointed place of meeting,

You are to make him stand in the presence of Eleazar the priest, who is to inquire on his behalf using the Urim in the presence of the LORD regarding a decision of judgment, because by his command he and all the Israelis with him will go out or come in."

Moses instructed the Israelis regarding everything that the LORD had commanded him.
