Yeremia 17:9

17:9 The human mind is more deceitful than anything else.

It is incurably bad. ¹  Who can understand it?

Matius 26:33-35

26:33 Peter ²  said to him, “If they all fall away because of you, I will never fall away!” 26:34 Jesus said to him, “I tell you the truth, ³  on this night, before the rooster crows, you will deny me three times.” 26:35 Peter said to him, “Even if I must die with you, I will never deny you.” And all the disciples said the same thing.

[17:9]  ¹ tn Or “incurably deceitful”; Heb “It is incurable.” For the word “deceitful” compare the usage of the verb in Gen 27:36 and a related noun in 2 Kgs 10:19. For the adjective “incurable” compare the usage in Jer 15:18. It is most commonly used with reference to wounds or of pain. In Jer 17:16 it is used metaphorically for a “woeful day” (i.e., day of irreparable devastation).

[17:9]  sn The background for this verse is Deut 29:18-19 (29:17-18 HT) and Deut 30:17.

[26:33]  ² tn Grk “answering, Peter said to him.” This is somewhat redundant and has been simplified in the translation. Here δέ (de) has not been translated.

[26:34]  ³ tn Grk “Truly (ἀμήν, amhn), I say to you.”
