'Beseech' in the Bible

I beseech you therefore, brethren, by the mercies of God, to present your bodies a living sacrifice, holy, acceptable to God, which is your spiritual service.

Now I beseech you, brethren, by our Lord Jesus Christ, and by the love of the Spirit, that ye strive together with me in your prayers to God for me;

Now I beseech you, brethren, mark them that are causing the divisions and occasions of stumbling, contrary to the doctrine which ye learned: and turn away from them.
