'Deal' in the Bible

He is able to deal gently with those who are ignorant and are going astray, since he is also subject to weakness.

We have a great deal to say about this, and it’s difficult to explain, since you have become too lazy to understand.

They are physical regulations and only deal with food, drink, and various washings imposed until the time of restoration.

so the Messiah was sacrificed once to take away the sins of many people. And he will appear a second time, not to deal with sin, but to bring salvation to those who eagerly wait for him.
