They gaped upon me with their mouths - Margin, as in Hebrew, "opened their mouths against me." That is, they opened their mouths wide as if they would devour me, as a lion does when he seizes upon his prey. In Psalm 22:7 they are represented as "opening" the mouth for another purpose - that of derision or scorn; here they are described as if they were fierce and wild beasts ready to fall upon their prey.
As a ravening and roaring lion - The word "ravening" means "voraciously devouring," and the allusion in the Hebrew word is to the lion as he tears his prey - טרף ṭâraph - rending it in pieces to devour it. All this is designed to denote the greediness with which the enemies of the Redeemer sought his life.

They gaped upon me - They were fiercely and madly beat on my destruction.

They gaped upon me with their mouths,.... Either by way of derision and contempt, Job 16:10; or belching out blasphemy against him, or rather, with the greatest vehemency, crying out "Crucify him, crucify him", Luke 23:21; and this they did
as a ravening and roaring lion, when it has got its prey and rejoices, Amos 3:4; and being in such hands, and encompassed about with such enemies, as Christ was in the garden, in the high priest's hall, and in Pilate's judgment hall, is a third reason or argument used by him with God his Father, to be near to him and not far from him.
