Albert Barnes Commentary Job 20:6

"Though his height mount up to the heavens, And his head reach unto the clouds;" — Job 20:6 (ASV)

Though his excellency mount up to the heavens - Though he attain to the highest pitch of honor and prosperity. The Septuagint renders this, “Though his gifts should go up to heaven, and his sacrifice should touch the clouds”—a sentence conveying a true and a beautiful idea, but which is not a translation of the Hebrew. The phrases, to go up to heaven, and to touch the clouds, often occur to denote anything that is greatly exalted or very high.

Thus, in Virgil:

It clamor coelo.

So Horace:

Sublimi feriam sidera vertice.

And again:

Attingit solium Jovis.

Compare Genesis 11:4: Let us build us a tower whose top may reach unto heaven. In Homer the expression not unfrequently occurs, τοῦ γὰρ κλέος οὐρανὸν ἵκει tou gar kleos ouranon hikei.

In Seneca (Thyest. Act. v. ver. 1, 2, 4,) similar expressions occur:

Aequalis astris gradior, et cunctos super
Altum superbo vertice attingens polum,
Dimitto superos: summa votorum attigi.

The language of Zophar would also well express the condition of many a hypocrite whose piety seems to be of the most exalted character, and who appears to have made most eminent attainments in religion. Such a man may seem to be a man of uncommon excellence. He may attract attention as having extraordinary sanctity. He may seem to have a remarkable spirit of prayer, and yet all may be false and hollow.

Men who design to be hypocrites usually aim to be eminent hypocrites; those who have true piety often, alas, aim at a much lower standard. A hypocrite cannot keep up appearances, or accomplish his purpose of imposing on the world, without the appearance of extraordinary devotedness to God; many a sincere believer is satisfied with much less of the appearance of religion. He is sincere and honest.

He is conscious of true piety, and he attempts to impose on no one. At the same time, he makes scarcely any attempt to be what the hypocrite wishes to appear to be; and hence, the man who appears to be the most eminently devoted to God may be a hypocrite - yet usually not long. His zeal dies away, or he is allowed to fall into open sin, and to show that he had no true religion at heart.
