Charles H. Spurgeon on Psalms 116:15

Saints. The persons among whom implicitly he reckons himself, styled saints, are in the original set out by a word (Mydymx) that imports an especial respect of God towards them. The root whence that word issueth signifieth mercy (dmx consecravit, benefecit). Whereupon the Hebrews have given such a name to a stork, which kind among fowls is the most merciful; and that not only the old to their young ones, as most are, but also the young ones to the old, which they use to feed and carry when through age they are not able to help themselves. This title is attributed to men in a double respect;

1. Passively, in regard of God's mind and affection to them;

2. Actively, in regard of their mind and affection to others. God's merciful kindness is great towards them; and their mercy and kindness are great towards their brethren. They are, therefore, by a kind of excellency and property styled "men of mercy." Isa 57:1. In regard of this double acceptation of the word, some translate it, "merciful, tender, or courteous," Ps 18:25. Others with a paraphrase with many words, because they have not one fit word to express the full sense, thus, "Those whom God followeth with bounty, or to whom God extendeth his bounty." This latter I take to be the most proper to this place; for the word being passively taken for such as are made partakers of God's kindness, it sheweth the reason of that high account wherein God hath them, even his own grace and favour. We have a word in English that in this passive signification fitly answereth the Hebrew, which is this, favourite. William Gouge.
