Introduction

The Book of Zechariah, attributed to the Hebrew prophet Zechariah, is included in the Twelve Minor Prophets in the Hebrew Bible.

Date

Zechariah's prophecies took place during the reign of Darius the Great, and were contemporary with Haggai in a post-exilic world after the fall of Jerusalem in 587/6 BC.

Author

Most modern scholars believe the Book of Zechariah was written by at least two different people.

Zechariah 1–8, sometimes referred to as First Zechariah, was written in the 6th century BC.

Zechariah 9–14, often called Second Zechariah, contains within the text no datable references to specific events or individuals but most scholars give the text a date in the 5th century BC.

Composition

The return from exile is the theological premise of the prophet's visions in chapters 1–6. Chapters 7–8 address the quality of life God wants his renewed people to enjoy, containing many encouraging promises to them. Chapters 9–14 comprise two "oracles" of the future.

An extract from BHFA Volume 5

Zechariah 9:9b

צַדִּיק              וְנוֹשָׁע           הוּא

he       and victorious         just

The form   וְנוֹשָׁע  in the MT is the niph'al part. act. m. sg. of the root  ישׁע with an active meaning in the hiph'il binyan namely, "to deliver, save," but with a passive meaning in the niph'al binyan namely, "to be victorious, to be liberated." The Greek Septuagint has σώζων meaning, "delivering."

An extract from BHFA Volume 5

Zechariah 14:19a

זֹאת     תִּהְיֶה      חַטַּאת     מִצְרָיִם

Egypt         the sin of         it will be         this

• YLT This is the punishment of the sin of Egypt,

• KJB This shall be the punishment of Egypt,

• NASB This will be the punishment of Egypt,

• ESV This shall be the punishment to Egypt

• NIV This will be the punishment of Egypt

 חַטַּאת 

Noun, f. sg. cstr. meaning, "sin, sin offering." This noun, stems from the verb  חָטָא which means, "to miss a goal, to go wrong, to sin."

The Greek Septuagint has η αμαρτία and the Vulgate has hoc erit peccatum Aegypti, both of them correctly translating the MT meaning as, "the sin of Egypt."

The Geneva Bible introduced the expression “the punishment of Egypt” into this verse. The Bishops Bible rendered this as “the plague of Egypt”. The King James translators accepted the wording of the Geneva Bible, and from there it has found almost universal acceptance into the modern English language translations.

It should be noted that John Calvin and his aggressively punitive theology, which affected the views of most Protestant religions, had been the driving force behind the Geneva Bible.
