Have all the workers of iniquity no knowledge? — i.e., are they so senseless as not to perceive the consequences of their wrong-doing? or if we point the verb as the LXX. and Vulg., “shall they not know?” i.e., they are sure to find out to what their wickedness is leading them.
Who eat up. — Literally, eating my people, they have eaten bread; on Jehovah they have not called, which is usually explained, as in Authorised Version, “to devour God’s people has been as usual and as regular as the daily meal.” Another rendering is “whilst eating my people they have eaten bread, regardless of Jehovah,” i.e., they have gone on in their security eating and drinking, with no thought of the vengeance preparing for them by the God of the oppressed race. Some, however, prefer to divide the two clauses, “Ah, they shall see — all the workers of iniquity who eat my people — they eat bread (i.e., live) regardless of Jehovah.” This makes a better parallelism. A comparison with Micah 3:3-4, suggests that this verse of the psalm was a proverbial saying. (For the image, comp. Jeremiah 10:25; and Homer’s “people-devouring kings.”)
