Say among the heathen that the LORD reigneth: the world also shall be established that it shall not be moved: he shall judge the people righteously. Say among the heathen that the Lord reigneth - Justin Martyr, in his dialogue with Trypho the Jew, quotes this passage thus: Ειπατε εν τοις εθνεσι, ὁ Κυριος εβασιλευσε απο του ξυλου, "Say among the nations, the Lord ruleth by the wood," meaning the cross; and accuses the Jews of having blotted this word out of their Bibles, because of the evidence it gave of the truth of Christianity. It appears that this reading did exist anciently in the Septuagint, or at least in some ancient copies of that work, for the reading has been quoted by Tertullian, Lactantius, Arnobius, Augustine, Cassiodorus, Pope Leo, Gregory of Tours, and others. The reading is still extant in the ancient Roman Psalter, Dominus regnavit a ligno, and in some others. In an ancient MS. copy of the Psalter before me, while the text exhibits the commonly received reading, the margin has the following gloss: Regnavit a ligno crucis, "The Lord reigns by the wood of the cross." My old Scotico - Latin Psalter has not a ligno in the text, but seems to refer to it in the paraphrase: For Criste regned efter the dede on the crosse. It is necessary, however, to add, that no such words exist in any copy of the Hebrew text now extant, nor in any MS. yet collated, nor in any of the ancient Versions. Neither Eusebius nor Jerome even refer to it, who wrote comments on the Psalms; nor is it mentioned by any Greek writer except Justin Martyr.
The world also shall be established - The word תבל tebel signifies the habitable globe, and may be a metonymy here, the container put for the contained. And many think that by it the Church is intended; as the Lord, who is announced to the heathen as reigning, is understood to be Jesus Christ; and his judging among the people, his establishing the holy Gospel among them, and governing the nations by its laws.
