Esias 63:16

16 For thou art our Father; for Abraham knew us not, and Israel did not acknowledge us, yet do thou, O Lord, our Father, deliver us: thy name has been upon us from the beginning.

Esias 63:16 In-Context

14 and as cattle through a plain: the Spirit came down from the Lord, and guided them: thus thou leddest thy people, to make thyself a glorious name.
15 Turn from heaven, and look from thy holy habitation and thy glory: where is thy zeal and thy strength? where is the abundance of thy mercy and of thy compassions, that thou hast withholden thyself from us?
16 For thou art our Father; for Abraham knew us not, and Israel did not acknowledge us, yet do thou, O Lord, our Father, deliver us: thy name has been upon us from the beginning.
17 Why hast thou caused us to err, O Lord, from thy way? has hardened our hearts, that we should not fear thee? Return for thy servants' sake, for the sake of the tribes of thine inheritance,
18 that we may inherit a small part of thy holy mountain.
