Verse 7. A thousand shall fall at thy side and ten thousand at thy right hand.‏

“So terribly may the plague rage among men that the bills of mortality may become very heavy and continue to grow ten times heavier still, yet shall such as this Psalm speaks of survive the scythe of death. It shall not come nigh to thee. It shall not be so near as to be at thy side, and yet not nigh enough to touch thee; like a fire it shall burn all around, yet shall not the smell of it pass upon thee. How true is this of the plague of moral evil, of heresy, and of backsliding. Whole nations are infected, yet the man who communes with God is not affected by the contagion; he holds the truth when falsehood is all the fashion. Professors all around him are plague smitten, the church is wasted, the very life of religion decays, but in the same place and time, in fellowship with God, the believer renews his youth, and his soul knows no sickness. In a measure this also is true of physical evil; the Lord still puts a difference between Israel and Egypt in the day of his plagues. Sennacherib’s army is blasted, but Jerusalem is in health.
‘Our God his chosen people saves
Amongst the dead, amidst the graves.'”

-Charles Spurgeon (Treasury of David, Vol 5-pp77-78)
