Zechariah 1:4

1:4 “Do not be like your ancestors, to whom the former prophets called out, saying, ‘The Lord who rules over all says, “Turn now from your evil wickedness,”’ but they would by no means obey me,” says the Lord.

Zechariah 7:12

7:12 Indeed, they made their heart as hard as diamond, ¹  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.

Zechariah 14:10

14:10 All the land will change and become like the Arabah ²  from Geba to Rimmon, ³  south of Jerusalem; and Jerusalem will be raised up and will stay in its own place from the Benjamin Gate to the site of the First Gate ⁴  and on to the Corner Gate, ⁵  and from the Tower of Hananel to the royal winepresses. ⁶ 

[7:12]  ¹ 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).

[14:10]  ¹ tn Or “like a plain” (similar KJV, NAB, NASB, NCV, NRSV, NLT); or “like a steppe”; cf. CEV “flatlands.” The Hebrew term עֲרָבָה (’aravah) refers to an arid plain or steppe, but can be used specifically as the name of the rift valley running from the Sea of Galilee via the Jordan Valley and the Dead Sea to the Gulf of Aqaba.

[14:10]  ² sn The expression from Geba to Rimmon is a way of indicating the extent of all Judah from north (2 Kgs 23:8) to south (Job 15:32; 19:7). Since Geba (Heb. גֶּבַע) means “hill” and Rimmon resembles the word for height (Heb. רָמָה, ramah), this could be a play on words suggesting that all the high country will be made low, like the great Arabah valley.

[14:10]  ³ tn Or “old gate” (NLT); or “former gate” (NRSV).

[14:10]  ⁴ sn From the Benjamin Gate…on to the Corner Gate marks the northern wall of the city of Jerusalem from east to west.

[14:10]  ⁵ sn From the Tower of Hananel to the royal winepresses indicates the extent of Jerusalem from north to south.
