Psalm 50:1 New English Translation

50 El, God, the Lord^[b] has spoken,
and summoned the earth to come from the east and west.^[c]

Psalm 50:1 sn Psalm 50. This psalm takes the form of a covenant lawsuit in which the Lord comes to confront his people in a formal manner (as in Isa 1:2-20). The Lord emphasizes that he places priority on obedience and genuine worship, not empty ritual.
Psalm 50:1 sn Israel’s God is here identified with three names: El (אֵל [ʾel], or “God”), Elohim (אֱלֹהִים [ʾelohim], or “God”), and Yahweh (יְהוָה [y^ehvah] 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.
Psalm 50:1 tn Heb “and calls [the] earth from the sunrise to its going.”
