'Cover' in the Bible

You must not give in to him or even listen to him; do not feel sympathy for him or spare him or cover up for him.

You must have a spade among your other equipment and when you relieve yourself outside you must dig a hole with the spade and then turn and cover your excrement.

When you cross the Jordan River to the land the Lord your God is giving you, you must erect great stones and cover them with plaster.

So when you cross the Jordan you must erect on Mount Ebal these stones about which I am commanding you today, and you must cover them with plaster.
