1 Samuel 26:5

26:5 So David set out and went to the place where Saul was camped. David saw the place where Saul and Abner son of Ner, the general in command of his army, were sleeping. Now Saul was lying in the entrenchment, and the army was camped all around him.

Luke 19:43

19:43 For the days will come upon you when your enemies will build ¹  an embankment ²  against you and surround you and close in on you from every side.

[19:43]  ¹ sn Jesus now predicted the events that would be fulfilled in the fall of Jerusalem in a.d. 70. The details of the siege have led some to see Luke writing this after Jerusalem’s fall, but the language of the verse is like God’s exilic judgment for covenant unfaithfulness (Hab 2:8; Jer 6:6, 14; 8:13-22; 9:1; Ezek 4:2; 26:8; Isa 29:1-4). Specific details are lacking and the procedures described (build an embankment against you) were standard Roman military tactics.

[19:43]  ² sn An embankment refers to either wooden barricades or earthworks, or a combination of the two.
