For the phrases “Your throne, O God, endures forever and ever. Your royal scepter is a scepter of equity; you love righteousness and hate wickedness. Therefore God, your God, has anointed you with the oil of gladness beyond your companions,” see Hebrews 1:8 and Hebrews 1:9.

Note that this quote in the New Testament is not taken from the Hebrew Bible but from the Greek Septuagint (LXX) which translates into English as “Your throne, O God, is forever and ever. A rod of equity is the rod of your rule; you loved righteousness and hated lawlessness. Therefore God, your God, anointed you with oil of rejoicing beyond your partners.” (Translation by NETS — for the Greek version see the title’s tooltip)
