Luke 19:43

A trench [χ α ρ α κ α]. Rev., correctly, as Tynd., a bank. Only here in New Testament. The word literally means a pointed stake, used in fortifying the intrenchments of a camp, and thence the palisade itself. In fortifying a camp or besieging a city, a ditch was dug round the entire circuit, and the earth from it thrown up into a wall, upon which sharp stakes were fixed. Every Roman soldier carried three or four of these stakes on the march. Wyc., with pale.

Keep thee in [σ υ ν ε ξ ο υ σ ι ν]. See on ch. Luke 4:38.
