Psalms 132:12 In-Context

10 For thy servant David's sake turn not away the face of thine anointed.
11 The LORD hath sworn in truth unto David; he will not turn from it; Of the fruit of thy body will I set upon thy throne.
12 If thy children will keep my covenant and my testimony that I shall teach them, their children shall also sit upon thy throne for evermore.
13 For the LORD hath chosen Zion; he hath desired it for his habitation.
14 This is my rest for ever: here will I dwell; for I have desired it.
