'Keeps' in the Bible

A fighting man, when he is with the army, keeps himself free from the business of this life so that he may be pleasing to him who has taken him into his army.

If we are without faith, still he keeps faith, for he will never be untrue to himself.

If therefore a man keeps himself clear of these latter, he himself will be for specially honourable use, consecrated, fit for the Master's service, and fully equipped for every good work.
