1 Israel’s God is here identified with three names: El (אֵל [’el], or “God”), Elohim (אֱלֹהִים [’elohim], or “God”), and Yahweh (יְהוָה [yéhvah] or “the Lord”). There is an obvious allusion here to Josh 22:22, the only other passage where these three names appear in succession. In that passage the Reubenites, Gadites, and half-tribe of Manasseh declare, “El, God, the Lord! El, God, the Lord! He knows the truth! Israel must also know! If we have rebelled or disobeyed the Lord, don’t spare us today!” In that context the other tribes had accused the trans-Jordanian tribes of breaking God’s covenant by worshiping idols. The trans-Jordanian tribes appealed to “El, God, the Lord” as their witness that they were innocent of the charges brought against them. Ironically here in Ps 50 “El, God, the Lord” accuses his sinful covenant people of violating the covenant and warns that he will not spare them if they persist in their rebellion.
2 Heb “and calls [the] earth from the sunrise to its going.”
