2 Corinthians 5:20; 2 Corinthians 8:4; 2 Corinthians 10:2

20 Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be ye reconciled to God.
4 Praying us with much intreaty that we would receive the gift, and take upon us the fellowship of the ministering to the saints.
2 But I beseech you, that I may not be bold when I am present with that confidence, wherewith I think to be bold against some, which think of us as if we walked according to the flesh.
