Psaume 109:20-30

20 Tel sera, de la part de l'Éternel, le salaire de mes adversaires, et de ceux qui disent du mal contre moi.
21 Mais toi, Éternel mon Dieu, agis en ma faveur, à cause de ton nom; selon la grandeur de ta bonté, délivre-moi!
22 Car je suis affligé et misérable, et mon cœur est blessé au-dedans de moi.
23 Je m'en vais comme l'ombre quand elle décline; je suis chassé comme la sauterelle.
24 Mes genoux chancellent par le jeûne; ma chair a perdu son embonpoint.
25 Je suis pour eux un sujet d'opprobre; en me voyant, ils hochent la tête.
26 Sois-moi en aide, Éternel mon Dieu!
27 Sauve-moi selon ta bonté, afin qu'ils sachent que c'est ta main, que c'est toi, Éternel, qui l'as fait.
28 Ils maudiront, toi tu béniras; ils s'élèvent, mais ils rougiront, et ton serviteur se réjouira.
29 Que mes adversaires soient revêtus de confusion, et couverts de leur honte comme d'un manteau!
30 Ma bouche louera hautement l'Éternel; je le célébrerai au milieu de la multitude.

Psaume 109:20-30 Meaning and Commentary

To the chief Musician, A Psalm of David. This psalm was written by David, under the inspiration of the Holy Spirit, concerning Judas the betrayer of Christ, as is certain from Acts 1:16 hence it is used to be called by the ancients the Iscariotic psalm. Whether the occasion of it was the rebellion of Absalom, as some, or the persecution of Saul, as Kimchi; and whoever David might have in view particularly, whether Ahithophel, or Doeg the Edomite, as is most likely; yet it is evident that the Holy Ghost foresaw the sin of Judas, and prophesies of that, and of the ruin and misery that should come upon him; for the imprecations in this psalm are no other than predictions of future events, and so are not to be drawn into an example by men; nor do they breathe out anything contrary to the spirit of Christianity, but are proofs of it, since what is here predicted has been exactly accomplished. The title in the Syriac version is, "a psalm of David when they created Absalom king without his knowledge, and for this cause he was slain; but to us it expounds the sufferings of the Christ of God;" and indeed he is the person that is all along speaking in this psalm.
