Hebrews 3:10

3:10 “Therefore, I became provoked at that generation and said, ‘Their hearts are always wandering ¹  and they have not known my ways.’

Hebrews 10:7

10:7 “Then I said, ‘Here I am: ²  I have come – it is written of me in the scroll of the book – to do your will, O God.’” ³ 

[3:10]  ¹ tn Grk “they are wandering in the heart.”

[10:7]  ² tn Grk “behold,” but this construction often means “here is/there is” (cf. BDAG 468 s.v. ἰδού 2).

[10:7]  ³ sn A quotation from Ps 40:6-8 (LXX). The phrase a body you prepared for me (in v. 5) is apparently an interpretive expansion of the HT reading “ears you have dug out for me.”
