Adam Clarke on Isaiah 59:17

For clothing "For his clothing" - תלבשת tilbosheth. "I cannot but think that this word, תלבשת tilbosheth, is an interpolation.

1. It is in no one ancient version.

2. It is redundant in the sense, as it is before expressed in בגדי bigdey.

3. It makes the hemistich just so much longer than it ought to be, if it is compared with the others adjoining.

4. It makes a form of construction in this clause less elegant than that in the others.

5. It might probably be in some margin a various reading for בגדי bigdey, and thence taken into the text.

This is more probable, as its form is such as it would be if it were in regimine, as it must be before נקם nakam." - Dr. Jubb. Two sorts of armor are mentioned: a breast-plate and a helmet, to bring righteousness and salvation to those who fear him; and the garments of vengeance and the cloak of zeal for the destruction of all those who finally oppose him, and reject his Gospel.
