Darby Bible Notes

account - This is a different word from that translated 'reckoned' in ch. 4.22,23 (both 'imputed' in A.V.). There, a man is judicially estimated such or such. here, a particular fault is put to a person's account. The former is found in Gal. 3.6 and 2Cor. 5.19; this only in Philem. 18.

KJV

13 (For until the law sin was in the world: but sin is not imputed when there is no law.
