Jesus's prayer in John 17 is filled with it, establishing the unity between Father and Son: "as **thou**, Father, art in me, and I in thee" [[John 17:21]]. It is also used in worship, as in the heavenly cry, "**Thou** art worthy, O Lord, to receive glory and honour and power: for **thou** hast created all things" [[Revelation 4:11]].
