Charles H. Spurgeon on Psalms 145:9

His tender mercies. The nature and force of the word Mymxr, is properly the bowels;that is, there are tender mercies in God (so we term it in the Benedictus). Not of the ordinary sort, slight, and such as pierce not deep, come not far; but such as come de profundis, from the very bowels themselves, that affect that part, make the bowels relent. And what bowels? Not the bowels of the common man (for then Mwem had been the right word), but Mmxr are the bowels of a parent (so, we said, the word signifies), and this adds much; adds to mercy stosgh, natural love;to one strong affection another as strong or stronger than it.

And what parent? the more pitiful of the twain, the mother. For Mxr (the singular of this word) is Hebrew for the womb. So as this, to the two former addeth the sex; the sex holden to be the more compassionate. Of all mercies, those of the bowels; and of all bowels, the bowels of a parent;and of the two parents, those of the mother:such pity as the mother takes of the children of her womb. Mercies are in God; such mercies are in God. "Over all." It is good news for us that these mercies are in God; but, better yet, that they are in him with a super —"over." But, best of all, that that super is a super omnia —"over all." Much is said in few words to mercy's praise when 'tis said, super omnia. Nihil supra were much, none above it: but it is written super omnia, above all. He that saith this leaves no more to say; there is no higher degree; super omnia is the superlative.

All that are above are not over. It is not above only, as an obelisk or Maypole, higher than all about them, but have neither shadow nor shelter; no good they do! Mercy hath a broad top, spreading itself over all. It is so above all, as it is over them, too. As the vault of this chapel is over us, and the great vault of the firmament over that; the super of latitude and expansion, no less than of altitude and elevation. And this to the end that all may retire to it, and take covert; it over them, and they under it. Under it, under the shadow of it, as of Esay's "great rock in the wilderness", from the heat:under it, under the shelter of it as of Daniel's "great tree", from the tempest. (Isa 32:2 Da 4:11-12). —Lancelot Andrewes.
