Lukas 12:50

12:50 I have a baptism ¹  to undergo, ²  and how distressed I am until it is finished!

Lukas 19:43

19:43 For the days will come upon you when your enemies will build ³  an embankment ⁴  against you and surround you and close in on you from every side.

[12:50]  ¹ sn The figure of the baptism is variously interpreted, as some see a reference (1) to martyrdom or (2) to inundation with God’s judgment. The OT background, however, suggests the latter sense: Jesus is about to be uniquely inundated with God’s judgment as he is rejected, persecuted, and killed (Ps 18:4, 16; 42:7; 69:1-2; Isa 8:7-8; 30:27-28; Jonah 2:3-6).

[12:50]  ² tn Grk “to be baptized with.”

[19:43]  ³ 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]  ⁴ sn An embankment refers to either wooden barricades or earthworks, or a combination of the two.
