Charles Ellicott Commentary Psalms 120:3

"What shall be given unto thee, and what shall be done more unto thee, Thou deceitful tongue?" — Psalms 120:3 (ASV)

What shall ... ?—Literally, What will he give to you, and what will he add to you, deceitful tongue? where it is better, as in the Authorized Version, to take the subject as indefinite and so render it in the passive voice. Thus, we essentially get the following question: “What more can be added to you (i.e., in the way of epithet), besides lying and false, you deceitful tongue?”

The answer is given by suggesting the usual metaphors for malicious speech: “the warrior’s sharpened arrows” (Jeremiah 9:8; Psalms 57:4); “fire” (James 3:6). Only here, both images are elaborated.

For the Hebrew word give with the sense of comparison, see 1 Samuel 1:16: Count (Hebrew, give) not thine handmaid for a daughter of Belial. Gesenius compares the use of the Greek τιθένμι, instead of νομίζειν. So, too, the word “add” has a similar sense (1 Kings 10:7; see margin).
