A.T. Robertson Commentary Luke 19:43

"For the days shall come upon thee, when thine enemies shall cast up a bank about thee, and compass thee round, and keep thee in on every side," — Luke 19:43 (ASV)

Shall cast up a bank (παρεμβαλουσιν χαρακα). Future active indicative of παρεμβαλλω, a double compound (παρα, εν, βαλλω) of long usage, finally in a military sense of line of battle or in camp. Here alone in the N.T. So also the word χαρακα (χαραξ) for bank, stake, palisade, rampart, is here alone in the N.T., though common enough in the old Greek.

Compass thee round (περικυκλωσουσιν σε). Future active indicative. Another common compound to make a circle (κυκλος) around (περ), though here only in the N.T.

Keep thee in (συνεξουσιν σε). Shall hold thee together on every side (παντοθεν). See about συνεχω on 4:38.
