Charles Ellicott Commentary Job 19:26

"And after my skin, [even] this [body], is destroyed, Then without my flesh shall I see God;" — Job 19:26 (ASV)

And though after my skin. —The word skin is probably employed according to the common metonymy of a part for the whole, to mean the body.

The overall phrase could mean, “After they have thus destroyed my skin,” or “after my skin has been thus destroyed”—or, “and after my skin has been destroyed—this shall be: that even from my flesh I shall see God.” This refers, probably, in the first instance, to his present personal faith, despite the corruption produced by his disease: “I can and do still see God, whom I know as my Redeemer.”

But it is perhaps more probably understood in contrast to this present knowledge, implying something yet to come when the Redeemer stands at the last upon the earth. This idea also seems to be expressed further in the following verse.
