The article introduces and compares two different commentaries on Psalm 18:5c LXX found in the writings of Eusebius of Caesarea Eclogae propheticae and Commentaria in Psalmos. The commentary in Eclogae is based on the Greek translation of Ps 18 in the Septuagint and is Christological. Verse Ps 18:5c LXX is expounded as a metaphor of the unity of the Godhead and the human body in the Son. The explanation in Commentaria uses nonSeptuagint Greek translations, it adopts a more literal reading according to which verses Ps 18:5c–7 LXX convey the sun´s dutiful service in the sky to its Creator and Lord. The commentary in Eclogae displays an in all probability earlier, theologically more courageous exegesis, the explanation in Commentaria is more biblical, with the elucidation of the passage with the Scripture itself (a reference to Genesis 1:16–17).
