counted ... righteousness - “a just and rewardable action.”
for - or, “unto,” to the procuring of righteousness, as in Rom 4:2; Rom 10:4. Here it was a particular act, not faith, nor its object Christ; and what was procured was not justifying righteousness, or what was to be rewarded with eternal life; for no one act of man’s can be taken for complete obedience. But it was that which God approved and rewarded with a perpetual priesthood to him and his descendants (Num 25:13; 1Ch 6:4, etc.).
