Charles H. Spurgeon on Psalms 55:15

Let death seize upon them, and let them go down quick into hell. The last part and end of sinners' lives is worst with them. They have in their lives been busily trading in the world, buying and selling, and getting gain and ruffling it in the world, but meanwhile by their sins they run deep in debt with God, and for want of interest in Christ to be their surety at death (it may be on the sudden) it comes to that of the psalmist, Let death seize upon them, and let them go down quick into hell. Death seizes on them unawares, as a sergeant or pursevant, casts them into prison, which is expressed by their going down quick into hell (as it is said Nu 16:32-33), that Korah and his company did. Anthony Tuckney, 1599-1670.
