1 Kings 8:25

Therefore now, Lord God of Israel, keep with thy servant David
my father that thou promisedst him
That as he had fulfilled one part of his promise respecting himself, his immediate successor, so that he would fulfil the other respecting his more remote offspring:

saying, there shall not fail thee a man in my sight, to sit on the
throne of Israel;
one of David's posterity to inherit his throne and kingdom, but with this proviso:

so that thy children takes heed to their way;
in what way they walk, and how they walk in it:

that they walk before me as thou hast walked before me;
meaning as David walked, see ( Psalms 132:11 Psalms 132:12 ) .
