Luke 1:4

1:4 so that you may know for certain the things you were taught.

Luke 8:46

8:46 But Jesus said, “Someone touched me, for I know that power has gone out from me.”

Luke 20:7

20:7 So they replied that they did not know where it came from.

Luke 21:20

The Desolation of Jerusalem

21:20 “But when you see Jerusalem surrounded by armies, then know that its desolation has come near.

Luke 21:30

21:30 When they sprout leaves, you see 10  for yourselves and know that summer is now near.

Luke 22:57

22:57 But Peter 11  denied it: “Woman, 12  I don’t know 13  him!”

tn Or “know the truth about”; or “know the certainty of.” The issue of the context is psychological confidence; Luke’s work is trying to encourage Theophilus. So in English this is better translated as “know for certain” than “know certainty” or “know the truth,” which sounds too cognitive. “Certain” assumes the truth of the report. On this term, see Acts 2:36; 21:34; 22:30; and 25:26. The meaning “have assurance concerning” is also possible here.

tn Or “you heard about.” This term can refer merely to a report of information (Acts 21:24) or to instruction (Acts 18:25). The scope of Luke’s Gospel as a whole, which calls for perseverance in the faith and which assumes much knowledge of the OT, suggests Theophilus had received some instruction and was probably a believer.

tn This is a consummative perfect. Jesus sensed that someone had approached him to be healed, as his reference to power makes clear. The perception underlies Jesus’ prophetic sense as well.

tn Here καί (kai) has been translated as “so” to indicate the implied result of the dilemma Jesus’ opponents faced.

sn Very few questions could have so completely revealed the wicked intentions of the religious leaders. Jesus’ question revealed the motivation of the religious leaders and exposed them for what they really were – hypocrites. They indicted themselves when they cited only two options and chose neither of them. The point of Luke 20:1-8 is that no matter what Jesus said in response to their question they were not going to believe it and would in the end use it against him.

sn See Luke 19:41-44. This passage refers to the events associated with the fall of Jerusalem, when the city is surrounded by armies.

tn Grk “her,” referring to the city of Jerusalem (the name “Jerusalem” in Greek is a feminine noun).

sn The phrase its desolation is a reference to the fall of the city, which is the only antecedent present in Luke’s account. The parallels to this in Matt 24:15 and Mark 13:14 refer to the temple’s desolation, though Matthew’s allusion is clearer. They focus on the parallel events of the end, not on the short term realization in a.d. 70. The entire passage has a prophetic “two events in one” typology, where the near term destruction (a.d. 70) is like the end. So the evangelists could choose to focus on the near time realization (Luke) or on its long term fulfillment, which mirrors it (Matthew, Mark).

10 tn Grk “seeing for yourselves, you know.” The participle βλέποντες (bleponte") has been translated as a finite verb due to requirements of contemporary English style.

11 tn Grk “he denied it, saying.” The referent (Peter) has been specified in the translation for clarity. The participle λέγων (legwn) is redundant and has not been translated.

12 sn Woman was a polite form of address (see BDAG 208-9 s.v. γυνή), similar to “Madam” or “Ma’am” used in English in different regions.

13 sn The expression “I do not know him” had an idiomatic use in Jewish ban formulas in the synagogue and could mean, “I have nothing to do with him.”
