בַּעֲב֤וּר דְּבָֽרְךָ֙ וּֽכְלִבְּךָ֔ עָשִׂ֕יתָ אֵ֥ת כָּל־הַגְּדוּלָּ֖ה הַזֹּ֑את לְהוֹדִ֖יעַ אֶת־עַבְדֶּֽךָ׃
For Thy word’s sake, and according to Thine own heart, hast Thou wrought all this greatness, to make Thy servant know it.
Rashi on II Samuel
Because of Your word. To fulfill that which You told Shmuel to make me king.
Rashi on II Samuel
And due to [the will of] Your Heart. It is Your will [that I become king] and not because I am worthy.
Rashi on II Samuel
Of which You have informed Your servant. The announcement of which You have informed me.16That my kingdom will be everlasting.
