Jamieson, Fausset and Brown on Job 6:27

27. literally, "ye cause" (supply, "your anger") [Umbreit], a net, namely, of sophistry [Noyes and Schuttens], to fall upon the desolate (one bereft of help, like the fatherless orphan);

and ye dig (a pit) for your friend--that is, try to ensnare him, to catch him in the use of unguarded language [Noyes]. (Psa 57:6); metaphor from hunters catching wild beasts in a pit covered with brushwood to conceal it. Umbreit from the Syriac, and answering to his interpretation of the first clause, has, "Would you be indignant against your friend?" The Hebrew in Job 41:6, means to "feast upon." As the first clause asks, "Would you catch him in a net?" so this follows up the image, "And would you next feast upon him, and his miseries?" So the Septuagint.
