e. all those with whom I have been on terms of friendship (same phrase, Jeremiah 38:22). Watched for my halting; i.e. either laid traps for me or waited for me to commit some error for them to take advantage of.
The phrase, "my halting," is borrowed (?) from Psalms 35:15; Psalms 38:18 (Hebrew). He will be enticed; viz. to say something on which a charge of treason can be based.
