5 And therefore that this vice may be cured, in the person of the Prophet himself it is said, “Arise, O God, and judge the earth”; for the earth swelled high when it crucified You: rise from the dead, and judge the earth. “For You shall destroy among all nations.” What, but the earth? That is, destroying those who savour of earthly things, or destroying the feeling itself of earthly lust and pride in believers; or separating those who do not believe, as earth to be trodden under foot and to perish. Thus by His members, whose conversation is in heaven, He judges the earth, and destroys it among all nations. But I must not omit to remark, that some copies have, “for You shall inherit among all nations.” This too may be understood agreeably to the sense, nor does anything prevent both meanings existing at once. His inheritance takes place by love, which in that He cultivates by His commands and gracious mercy, He destroys earthly desires.
