15:2 The vine - tree - Israel is here compared to a vine, which, when fruitless, is utterly unprofitable. This the prophet minds them of to humble them, and awaken them to fruitfulness. A branch - One branch of a tree in the forest is of more use than the whole vine - tree is, except for its fruit.

15:3 A pin - Will it afford even a pin to drive into a wall or post, on which you may safely fasten any weight.

15:4 For fuel - When for its barrenness it is cut down, it is fit only to burn.

15:6 Given - Doomed for food to the fire.

15:8 Because - They have been so perpetually trespassing, that it seems a continued act.
