John Gill Commentary Psalms 119:83

"For I am become like a wine-skin in the smoke; Yet do I not forget thy statutes." — Psalms 119:83 (ASV)

For I am become like a bottle in the smoke
Like a bottle made of the skins of beasts, as was usual in those times and countries: hence we read of old and new bottles, and of their rending, (Judges 9:13) (Matthew 9:17) .

Now such a bottle being hung up in a smoky chimney, would be dried and shrivelled up, and be good for nothing; so Jarchi's note is, "like a bottle made of skin, which is dried in smoke;" and the Targum is, "like a bottle that hangs in smoke."

It denotes the uncomfortable condition the psalmist was in, or at least thought himself to be in; as to be in the midst of smoke is very uncomfortable, so was he, being in darkness, and under the hidings of God's face; black and sooty, like a bottle in smoke, with sin and afflictions; like an empty bottle, had nothing in him, as he was ready to fear; or was useless as such an one, and a vessel in which there was no pleasure; like a broken one, as he elsewhere says, despised and rejected of men.

It may also have respect unto the form of his body, as well as the frame of his mind; he who before was ruddy, and of a beautiful countenance, now was worn out with cares and old age, was become pale and wrinkled, and like a skin bottle shrivelled in smoke;

[yet] do I not forget thy statutes ;
he still attended to the word, worship, ways and ordinances of the Lord; hoping in due time to meet with comfort there, in which he was greatly in the right.
