Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

The prophet sees this as he prays, and now feasts himself on the consequences of this victory of Jehovah, prophesying in Isa 33:5, Isa 33:6 : "Jehovah is exalted; for, dwelling on high, He has filled Zion with justice and righteousness. And there will be security of thy times, riches of salvation, of wisdom, and knowledge. Fear of Jehovah is then the treasure of Judah." Exalted: for though highly exalted in Himself, He has performed an act of justice and righteousness, with the sight and remembrance of which Zion is filled as with an overflowing rich supply of instruction and praise. A new time has dawned for the people of Judah. The prophet addresses them in Isa 33:6; for there is nothing to warrant us in regarding the words as addressed to Hezekiah. To the times succeeding this great achievement there would belong 'emūnâh, i.e., (durability (Exo 17:12) - a uniform and therefore trustworthy state of things (compare Isa 39:8, "peace and truth"). Secondly, there would also belong to them חסן, a rich store of salvation, wisdom, and knowledge (compare the verb in Isa 23:18). We regard these three ideas as all connected with chōsen. The prophet makes a certain advance towards the unfolding of the seven gifts in Isa 11:2, which are implied in "salvation;" but he hurries at once to the lowest of them, which forms the groundwork of all the rest, when he says, thirdly, that the fear of Jehovah will be the people's treasure. The construct form, chokhmath, instead of chokhmâh, is a favourite one, which Isaiah employs, even apart from the genitive relation of the words, for the purpose of securing a closer connection, as Isa 35:2; Isa 51:21 (compare pârash in Eze 26:10), clearly show. In the case before us, it has the further advantage of consonance in the closing sound.
