Melachim Alef 8:25

Therefore now, HASHEM Elohei Yisroel, be shomer with Thy eved Dovid Avi that Thou promised him, saying, There shall not Yikaret (be cut off, fail) thee an ish in My sight to sit on the Kisse Yisroel; so that thy banim be shomer over their derech, that they walk before Me as thou hast walked before Me.
