Zechariah wrote to the people of Judah who returned from exile in Babylon. The people of Judah continued to sin as their ancestors had before they went into exile. Zechariah called the people to repent and to obey Yahweh. And he called them to renew the covenant with Yahweh. Zechariah also prophesied about the Messiah (6:12) and Israel's final victory over their enemies. (See: [[rc://en/tw/dict/bible/kt/covenant]])
Translators may decide to translate the traditional title “The Book of Zechariah” in a way that is clearer to the readers. They may decide to call it the "The Book About Zechariah" or "The Sayings of Zechariah." (See: rc://en/ta/man/translate/translate-names)
The name "Israel" is used in many different ways in the Bible. There was a man named Jacob. God changed his name to Israel. The descendants of Jacob became a nation also called Israel. Eventually, the nation of Israel split into two kingdoms. The northern kingdom was named Israel. The southern kingdom was named Judah. Zechariah uses the term "Israel" to refer to both the nation of Israel and the northern kingdom of Israel.
Zechariah presented the Messiah as both a king and a shepherd. Zechariah said that the Messiah would come and deliver his people. However, he would also be pierced (12:10) and struck with the sword (13:7). (See: rc://en/tw/dict/bible/kt/christ]])
Zechariah often spoke of the last days by using the phrase "that day" or "in that day." When referencing a future "day," the translator should be aware that it is possible that the author is speaking about the last days. (See: [[rc://en/tw/dict/bible/kt/lastday]])
