In his hand are the deep places of the earth: the strength of the hills is his also.

For in his hand are all the ends of the earth: and the heights of the mountains are his.

In whose hand are the deep places of earth, And the strong places of hills are His.

The deep places of the earth are in his hand; and the tops of the mountains are his.

In his hand - In his power, or under his control as his own. That is, he so possesses all things that they can be claimed by no other. His right over them is absolute and entire.
Are the deep places of the earth - The word used here - מחקר mechqâr - means the interior, the inmost depth; that which is "searched out," from - חקר châqar - to search, search out, explore. The primary idea is that of searching by boring or digging; and the allusion here is to the parts of the earth which could be explored only by digging - as in mining, or sinking shafts in the earth. The meaning is, that all those places which lie beyond the ordinary power of observation in man are in the hand of God. He knows them as clearly as those which are most plain to human view; he possesses or owns them as his own as really as he does those which are on the surface of the ground.
The strength of the hills is his also - Margin, "The heights of the hills are his." The word rendered "strength" - תועפות tô‛âphôth - means properly swiftness or speed in running; then, weariness, wearisome labor; and hence, wealth obtained by labor; "treasures." Here the expression means "treasures of the mountains;" that is, treasures obtained out of the mountains, the precious metals, etc. Compare the notes at Job 22:25, where the same word occurs. All this belongs to God. As he is the Maker of these hills, and of all that they contain, the absolute proprietorship is in him.

In his hand are the deep places of the earth - The greatest deeps are fathomed by him.
The strength of the hills is his also - And to him the greatest heights are accessible,

In his hand [are] the deep places of the earth: the (c) strength of the hills [is] his also.

In his hand are the deep places of the earth,.... The "penetrals" (c) of it; not only what are penetrated by men, the minerals that are in it; but what are of such deep recess as to be penetrated only by the Lord himself; these are in the hands and power of Christ, which he can search into, discover, and dispose of; these are the foundations of the earth, which cannot be searched out beneath by men, Jeremiah 31:37,
the strength of the hills is his also; or, "the wearinesses" (d) of them, the tops (e) of them, which make a man weary to go up unto, they are so high; the Targum is,
"the strengths of the height of the hills;''
which takes in both ideas, both the height and strength of them. The hills, that are both high and strong, are set fast by his power, and are at his command; and bow and tremble before him, whom men ought to worship.
(c) "penetralia terrae", Musculus, Piscator, Gejerus, Michaelis. (d) "lassitudines", Gejerus. (e) "Cacumina", Montanus, Tigurine version, Musculus.
