Adam Clarke on Deuteronomy 28:30

Thou shalt betroth a wife, etc. - Can any heart imagine any thing more grievous than the evils threatened in this and the following verses? To be on the brink of all social and domestic happiness, and then to be suddenly deprived of all, and see an enemy possess and enjoy every thing that was dear to them, must excite them to the utmost pitch of distraction and madness. They have, it is true, grievously sinned; but, O ye Christians, have they not grievously suffered for it? Is not the stroke of God heavy enough upon them? Do not then, by unkind treatment or cruel Oppression, increase their miseries. They are, above all others, the men who have seen affliction by the stroke of his rod; Lam 3:1.
