Matthew 5:18

5:18 I ¹  tell you the truth, ²  until heaven and earth pass away not the smallest letter or stroke of a letter ³  will pass from the law until everything takes place.

Matthew 24:34-35

24:34 I tell you the truth, ⁴  this generation ⁵  will not pass away until all these things take place. 24:35 Heaven and earth will pass away, but my words will never pass away. ⁶ 

[5:18]  ¹ tn Grk “For I tell.” Here an explanatory γάρ (gar) has not been translated.

[5:18]  ² tn Grk “Truly (ἀμήν, amhn), I say to you.”

[5:18]  ³ tn Grk “Not one iota or one serif.”

[24:34]  ⁴ tn Grk “Truly (ἀμήν, amhn), I say to you.”

[24:34]  ⁵ sn This is one of the hardest verses in the gospels to interpret. Various views exist for what generation means. (1) Some take it as meaning “race” and thus as an assurance that the Jewish race (nation) will not pass away. But it is very questionable that the Greek term γενεά (genea) can have this meaning. Two other options are possible. (2) Generation might mean “this type of generation” and refer to the generation of wicked humanity. Then the point is that humanity will not perish, because God will redeem it. Or (3) generation may refer to “the generation that sees the signs of the end” (v. 30), who will also see the end itself. In other words, once the movement to the return of Christ starts, all the events connected with it happen very quickly, in rapid succession.

[24:35]  ⁶ sn The words that Jesus predicts here will never pass away. They are more stable and lasting than creation itself. For this kind of image, see Isa 40:8; 55:10-11.
