Zechariah 1:15

1:15 But I am greatly displeased with the nations that take my grace for granted. ¹  I was a little displeased with them, but they have only made things worse for themselves.

Zechariah 7:12

7:12 Indeed, they made their heart as hard as diamond, ²  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.

[1:15]  ¹ tn Or “the nations that are at ease” (so ASV, NRSV). The Hebrew word in question is שַׁאֲנָן (sha’anan) which has the idea of a careless, even arrogant attitude (see BDB 983 s.v. שַׁאֲנָן); cf. NAB “the complacent nations.” Here it suggests that the nations take for granted that God will never punish them just because he hasn't already done so. Thus they presume on the grace and patience of the Lord. The translation attempts to bring out this nuance rather than the more neutral renderings of TEV “nations that enjoy quiet and peace” or NLT “enjoy peace and security.”

[7:12]  ² 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).
