Charles H. Spurgeon on Psalms 93:2

Thy throne is established of old. Lest any one should suspect that the royal dignity depicted and demonstrated in the previous verse by the creation of the world, which was the effect of kingly power and majesty, was a new thing or came into existence yesterday or the day before, or that God had recently obtained the office of ruling and governing, or that by long use and experience he had acquired skill, or held a somewhat foreign throne as other kings are wont, he says that this dignity is as ancient as creation itself, so that the throne of this kingdom was founded at the very time when the foundations of the earth were laid; and as the earth was established by him as his footstool, so the heaven was his throne, (Isa 66:1), which endures for ever. Especially does he teach that from eternity, before the formation of the world, God always remained the same in himself, not needing creation or any creature, thereby to obtain any new perfection. Lorinus.
