Psalm 45:11 New English Translation

¹¹Then^[a] the king will be attracted by^[b] your beauty.
After all, he is your master. Submit^[c] to him.^[d]

Psalm 45:11 tn After the preceding imperatives, the jussive verbal form with vav (ו) conjunctive is best understood as introducing a purpose (“so that the king might desire your beauty”) or result clause (see the present translation and cf. also NASB). The point seems to be this: The bride might tend to be homesick, which in turn might cause her to mourn and diminish her attractiveness. She needs to overcome this temptation to unhappiness and enter into the marriage with joy. Then the king will be drawn to her natural beauty.
Psalm 45:11 tn Or “desire.”
Psalm 45:11 tn Or “bow down.”
Psalm 45:11 sn Submit to him. The poet here makes the point that the young bride is obligated to bring pleasure to her new husband. Though a foreign concept to modern western culture, this was accepted as the cultural norm in the psalmist’s day.
