Banded together [π ο ι η σ α ν τ ε ς σ υ σ τ ρ ο φ η ν]. Lit., having made a conspiracy. See on concourse, ch. 19 40.

Bound themselves under a curse [α ν ε θ ε μ α τ ι σ α ν ε α υ τ ο υ ς]. Lit., anathematized or cursed themselves; invoked God's curse on themselves if they should violate their vow.
