הַנּוֹתֵ֥ן תְּשׁוּעָ֗ה לַמְּלָ֫כִ֥ים הַ֭פּוֹצֶה אֶת־דָּוִ֥ד עַבְדּ֗וֹ מֵחֶ֥רֶב רָעָֽה׃
주는 왕들에게 구원을 베푸시는 자시요 종 다윗을 그 해하는 칼에서 구하시는 자시니이다
Rashi on Psalms
Who gives salvation to kings This speaks about the Rock of the Divisions, when David was close to being seized by Saul (I Sam. 23:27): “A messenger came to Saul, saying, ‘Make haste and go, etc.’” He saved Saul from shedding innocent blood, and David from being killed.
