Matthew Poole and continuators on Job 17:16

16. They shall go down to the bars of the pit , when our rest together is in the dust .

Either 1. They that would see my hope, they must go into the Grave to behold it. Or rather 2. My hopes of which he spake in the singular number, v. 15. which he here changeth into the plural, as is very usual in these Poetical Books.

i. e. Into the closest and innermost parts of the Pit: My hopes are dying, and will be buried in my Grave.

So the sense is, when those Spectators, together with my self shall be in our Graves. Heb. Seeing that (as this Hebrew Particle, im, oft signifies: or, certainly, as it is used Numb. 17. 13. Iob 6. 13. and elsewhere,) our rest shall be together in the dust, i. e. I and my hopes shall be buried together.
