Job 38:6

“Whereupon are the foundations thereof fastened? etc.] Or the pillars of it, as Ben Gersom interprets it; (see <197503>Psalm 75:3); and which Aben Ezra understands of the mountains: but be they what they may, on what can they be fastened or sunk into, when the earth hangs on nothing, and there is nothing visible to support it, nothing but the mighty hand of God? or who laid the corner stone thereof? which unites, cements, and keeps the fabric together, and is the ornament and beauty of it; but who can tell what that is? Aben Ezra interprets it of the point or centre of the earth.”

“foundations--not "sockets," as Margin. fastened--literally, "made to sink," as a foundation-stone let down till it settles firmly in the clay (Job 26:7). Gravitation makes and keeps the earth a sphere.”

“Whereupon are the foundations - Margin, “sockets.” The Hebrew word (אדן 'eden) means “a basis,” as of a column, or a pedestal; and then also the foundation of a building. The language here is evidently figurative, comparing the earth with an edifice. In building a house, the securing of a proper foundation is essential to its stability; and here God represents himself as rearing the earth on the most permanent and solid basis. The word is not used in the sense of sockets, as it is in the margin. Fastened - Margin, “made to sink.” The margin rather expresses the sense of the Hebrew word הטבעוּ hāṭâba‛û. It is rendered “sink” and “sunk” in Psalms 69:2, Psalms 69:14; Psalms 9:15;…”

“Foundations - This strong and durable building hath no foundations but God's power, which hath marvelously established it upon itself. Cornerstone - By which the several walls are joined and fastened together, and in which, next to the foundations, the stability of a building consists. The sense is, who was it that built this goodly fabrick, and established it so firmly that it cannot be moved. Job 38:7”
