וּשְׁלֹמֹ֕ה יָשַׁ֕ב עַל־כִּסֵּ֖א דָּוִ֣ד אָבִ֑יו וַתִּכֹּ֥ן מַלְכֻת֖וֹ מְאֹֽד׃
И сел Соломон на престоле Давида, отца его; и его королевство было твердо установлено.
Rashi
And it will come to pass when your days are finished to go with your forefathers That is to say, do not fear that I will hasten the matter, but when your days are finished, then it will come about, and I shall raise up your seed after you. and I shall establish his kingdom And so he says of Solomon, (I Kings 2:12): “... and his kingdom was firmly established.”
