Isaiah 46:12

46:12 Listen to me, you stubborn people, ¹ 

you who distance yourself from doing what is right. ² 

Psalms 78:8

78:8 Then they will not be like their ancestors,

who were a stubborn and rebellious generation,

a generation that was not committed

and faithful to God. ³ 

Zechariah 7:11-12

7:11 “But they refused to pay attention, turning away stubbornly and stopping their ears so they could not hear. 7:12 Indeed, they made their heart as hard as diamond, ⁴  so that they could not obey the Torah and the other words the Lord who rules over all had sent by his Spirit through the former prophets. Therefore, the Lord who rules over all had poured out great wrath.

[46:12]  ¹ tn Heb “strong of heart [or, mind]”; KJV “stouthearted”; NAB “fainthearted”; NIV “stubborn-hearted.”

[46:12]  ² tn Heb “who are far from righteousness [or perhaps, “deliverance”].”

[78:8]  ³ tn Heb “a generation that did not make firm its heart and whose spirit was not faithful with God.” The expression “make firm the heart” means “to be committed, devoted” (see 1 Sam 7:3).

[7:12]  ⁴ tn The Hebrew term שָׁמִיר (shamir) means literally “hardness” and since it is said in Ezek 3:9 to be harder than flint, many scholars suggest that it refers to diamond. It is unlikely that diamond was known to ancient Israel, however, so probably a hard stone like emery or corundum is in view. The translation nevertheless uses “diamond” because in modern times it has become proverbial for its hardness. A number of English versions use “flint” here (e.g., NASB, NIV).
