Matthew 10:16

I send you forth [ε γ ω α π ο σ τ ε λ λ ω]. Cognate to the word ajpostolov (apostle). The I is emphatic : "It is I that send you forth."

They were to imitate the serpent's wariness, but not his wiliness. "The presence of the wolves demands they ye be wary; the fact that ye are my apostles (compare" I send you ") demands that ye be guileless " (Dr. Morison on Matthew).
