Psalms 89:37

37 As the moon it is established -- to the age, And the witness in the sky is stedfast. Selah.

Psalms 89:37 In-Context

35 Once I have sworn by My holiness, I lie not to David,
36 His seed is to the age, And his throne [is] as the sun before Me,
37 As the moon it is established -- to the age, And the witness in the sky is stedfast. Selah.
38 And Thou, Thou hast cast off, and dost reject, Thou hast shown Thyself wroth With Thine anointed,
39 Hast rejected the covenant of Thy servant, Thou hast polluted to the earth his crown,
