Yet have I set my king upon my holy hill of Zion.
Ver. 6. Yet have I set my king] Heb. And I have set. Heb. I have anointed; where the sign of his inauguration, or entrance into his kingdom, is put for the possession and enjoying thereof. David was anointed by God's appointment; Christ was also anointed and appointed by his Father to the office and work of a mediator; and is therefore here called his king. And, is here a sign of indignation stirred.
Upon mine holy hill of Zion] David's strong hold, and a figure of the Church, Heb 12:22 Rev 14:1 Isaiah 60:14, as being the seat of the kingdom, a sanctuary. Out of Zion also went forth the law, and the word of the Lord out of Jerusalem, Isaiah 2:3 : it signifieth a watch tower. In the Church Christ, angels, ministers, common Christians, watch against enemies visible and invisible.
