John Gill's Exposition of the Whole Bible
Proverbs 12:10
A righteous [man] regardeth the life of his beast,.... Or "knoweth" it q; knows the worth of it and values it, and takes care of it, and is concerned for the preservation of it; he provides sufficient food for it, and gives it; he does not overwork it, but allows it proper rest from labour; and, if in any disorder, will make use of all suitable means to heal it; see an instance of the care of Jacob, that righteous man, of his cattle, Genesis 33:14; and, on the other hand, see an instance of a wicked man's cruelty to his beast in Balaam, for which he was reproved, Numbers 22:28; by various laws and rules which God has given, it is his will that men should be merciful to their beasts, Deuteronomy 25:4; and such who are so will be more especially pitiful and tenderhearted to their fellow creatures;
but the tender mercies of the wicked [are] cruel; or "[are] the mercies of a cruel one" r; the most tender things which are expressed or done by them are nothing but cruelty; and what then must be their more severe expressions and actions? so the most tender concern which antichrist and his followers show to the souls of men breathes nothing but cruelty; the compassionate methods they take to convert heretics, as they call them, are dark dungeons and stinking prisons, racks and tortures, fire and faggots; these are their wholesome severities; this their kindness to men, to deliver them up to the secular power, to inflict pains and punishments on them the most grievous to save their souls. Thus, while the beast of Rome looks like a lamb, he speaks like a dragon, and exercises all the cruelty of the first beast, Rome Pagan,
