[As for] the head of those that compass me about, let the,mischief of their own lips cover them. Meaning either their natural head, put for their whole persons; and the sense is, let the mischief they have contrived for others fall upon themselves; see Eze 9:10 Ps 7:16; or some principal person, the head and leader of them, as the word is sometimes used, Isa 9:14; and designs either Saul, who at the head of three thousand men surrounded the hill where David and his men were; or Doeg the Edomite, who was over the servants of Saul, and accused David to him; so Kimchi: or Ahithophel, who was at the head of the conspirators against him; so the Targum paraphrases it,"Ahithophel, the head of the sanhedrim of the disciples of wickedness.'
'If we understand this clause of Christ, the antitype of David, it may design Judas; who was the guide to them that sought Jesus, and, at the head of a band of men, enclosed and took him: or if of the church and people of God, the man of sin may be intended, the pope of Rome; the head over many countries, the antichristian nations, Ps 110:6.
