'Beseech' in the Bible

Wherefore I beseech you to confirm your love toward him.

We are ambassadors therefore on behalf of Christ, as though God were entreating by us: we beseech you on behalf of Christ, be ye reconciled to God.

yea, I beseech you, that I may not when present show courage with the confidence wherewith I count to be bold against some, who count of us as if we walked according to the flesh.
