Isaiah 33:2

“O Lord, be gracious unto us, &c.] This is a prayer of the church under the persecutions of antichrist, imploring the grace and favour of God in their miserable and distressed circumstances; desiring his gracious help, assistance, and deliverance; pleading not any merits of their own, but casting themselves upon the mercy and kindness of God: we have waited for thee; time after time, year after year, in the use of means; hoping for the manifestations of thyself, and kind appearance for us; expecting help and salvation, and still continue to wait, believing the time will come when favour will be shown: be thou their arm every morning; when they pray unto thee, the morning being the time of…”

“O Lord - This is a solemn prayer to Yahweh, made by the Jews in the apprehension of the invasion of the Assyrian. It is not meant that this prayer was actually offered, but it is a prophetic representation indicating the alarm of the Jews at his approach, and their disposition to throw themselves upon the mercy of God. We have waited for thee - That is, we have looked for deliverance from this threatened invasion from thy hand (compare the note at Isaiah 26:8). Be thou their arm - The arm is a symbol of strengh. It is used in the Scriptures as emblematic of the divine protection, or of the interposition of God in time of calamity and dancer Exodus 15:16; Job 40:9; Psalms 44:3; Psalms 77:15;…”

“O Lord - The prophet contemplating the judgment which was now coming upon God's people, directs his prayer to God for them. Their arm - Our arm or strength. The change of persons is frequent in prophetical writings. Every morning - When we offer the morning sacrifice, and call upon thee: which yet is not meant exclusively, as if he did not desire God's help at other times; but comprehensively, the morning being put for the whole day. The sense is, help us speedily and continually. Isaiah 33:3”

“33:2 The godly community prayed for God to be merciful in response to the promise of 30:18.”

“In Isa 33:2 the prophet's word of command is changed into a believing prayer: "Jehovah, be gracious to us; we wait for Thee: be their arm with every morning, yea, our salvation in time of need!" "Their arm," i.e., the power which shelters and defends them, viz., Thy people and my own. "Yea," 'aph, is emphatic. Israel's arm every morning, because the danger is renewed every day; Israel's salvation, i.e., complete deliverance ( Isa 25:9), because the culminating point of the trouble is still in prospect.
