Psalms 27:3

Though an host should encamp against me,.... An host of the ungodly, as the Targum; though ever so many of them, even ten thousands of them, as in Psalms 3:6; should beset him on every side;

my heart shall not fear; for not only the angels of the Lord encamped about him, as they do about all that fear the Lord; but salvation was appointed for walls and bulwarks about him; yea, the Lord himself was a wall of fire around him, and he was kept as in a garrison by the power of God;

though war should rise against me: in all its terrible shapes:

in this [will] I [be] confident; either in this war, in the midst of it; or in this that he had expressed, Psalms 27:1; that the Lord was his light, his salvation, and the strength of his life; so the Jewish writers e: or as others f, in this one thing, desired in Psalms 27:4; but either of the former senses is best, especially the latter of them. Saints need not be afraid, though there is a war within them between the flesh and spirit; and though without are fightings with Satan and his principalities and powers; since they may be confident of victory, and that they are more than conquerors, through Christ that has loved them.
