Psalm 50 is the first of twelve psalms (the others are 73-83) ascribed by tradition to Asaph, head of one of the Levitical choirs (1 Chron. 6:31-48). It is unusual among the psalms in that, for the most part, it represents God's address to Israel rather than Israel's address to God.
For Christians who sing this psalm, the LORD appears in Zion to confront the people (st. 1), to call them to covenant account. After summoning the covenant witnesses–the earth (v. 1) and the heavens (v. 4)–the LORD calls for an assembly of all "who made a covenant" with him (v. 5; st. 2). First God instructs them with warnings against false notions about sacrifice, exhorting them, "Call upon me" (v. 15; st. 3-5). Then God turns to the wicked with indictments and rebukes, making clear that God desires people's complete trust and a wholehearted commitment to his moral will (st. 6-8).
Marie J. Post (PHH 5) prepared this versification in 1985 for the Psalter Hymnal using the 1912 Psalter as her starting point.
