The LORD of hosts is with us; the God of Jacob is our refuge. Selah.
The LORD of hosts is with us; the God of Jacob is our refuge. See Gill on "Psalms 46:7". The Targum paraphrases it, "the Word of the Lord of hosts", as in Psalms 46:7; and the same words are here repeated, to comfort those that were fearful and unbelieving, with which the church then comforted herself.
Selah; on this word, See Gill on "Psalms 3:2".
