NET

20 Therefore we are ambassadors for Christ, as though God were making his plea through us. We plead with you on Christ’s behalf, “Be reconciled to God!”

Darby

20 We are ambassadors therefore for Christ, God as [it were]^D8437 beseeching by us, we entreat for Christ, Be reconciled to God.

Darby Bible Notes

[it were] - 'As of God beseeching;' 'as though,' or 'as if,' is too much similarity or comparison. God being in Christ, and they Christ's ambassadors, they besought on God's behalf. He was as beseeching by them. The apostle will not say God was beseeching, but softens it by 'as it were.' yet it amounted to that, as done on his behalf. It is difficult to translate, though the sense is most evident and beautiful.

KJV

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.
