(1) The King James Version and the ASV render Is. 34:16: "my mouth, it hath commanded, and his Spirit, it hath gathered them."
(2) At Numbers 11:17 we see: "I will take ['some' - NRSV, NJB] of the Spirit which is upon thee, and will put it upon them" - ASV (compare KJV, RSV, NRSV, AT, LB, NEB, REB, NAB, JB, NJB, Beck).
(3) The same usage is found at Numbers 11:25 in those same trinitarian Bibles: "it." (Compare the Septuagint.) This is God's Holy Spirit - Numbers 11:29.
(4) John 14:17 uses neuter pronouns ('which,' 'it') for the holy spirit in the actual NT manuscripts and texts. It is purposely mistranslated in most trinitarian Bibles.
(5) Romans 8:16 uses the neuter "itself" for the holy spirit in the actual NT manuscripts and texts. The KJV translates it correctly.
(6) Romans 8:26 uses the neuter "itself" for the holy spirit in the actual NT manuscripts and texts. The KJV translates it correctly.
