The good man is perished out of the earth: and there is none upright among men: they all lie in wait for blood; they hunt every man his brother with a net. The good man is perished out of the earth - A similar sentiment may be found, Psalms 12:1; Isaiah 57:1. As the early fig of excellent flavor cannot be found in the advanced season of summer, or a choice cluster of grapes after vintage, so neither can the good and upright man be discovered by searching in Israel. This comparison, says Bp. Newcome, is beautifully implied.
They hunt every man his brother with a net - This appears to be an allusion to the ancient mode of duel between the retiarius and secutor. The former had a casting net, which he endeavoured to throw over the head of his antagonist, that he might then despatch him with his short sword. The other parried the cast; and when the retiarius missed, he was obliged to run about the field to get time to set his net in right order for another throw. While he ran, the other followed, that he might despatch him before he should be able to recover the proper position of his net; and hence the latter was called secutor, the pursuer, as the other was called retiarius, or the net man. I have explained this before on Job, and other places; but because it is rarely noticed by commentators, I explain the allusion here once more. Abp. Newcome by not attending to this, has translated איש את אחיהו יצודו חרם ish eth achihu yatsudu cherem, "They hunt every man his brother for his destruction;" though he put net in the margin.
