Zechariah 7:10

Evil against his brother in your heart - Do not indulge an unfavourable opinion of another: do not envy him; do not harbour an unbrotherly feeling towards him.

imagine evil--that is, devise evil. The Septuagint takes it, Harbor not the desire of revenge (Lev 19:18). "Devise evil against one another" is simpler (Psa 36:4; Mic 2:1).

Yea, they made their hearts as an adamant stone,.... The word here used is translated a "diamond" in Jer 17:1 and it is said to be harder than a flint, Eze 3:9. The Jewish writers say (g) it is a worm like a barley corn, so strong as to cut the hardest stones in pieces; Moses (they say) used it in hewing the stones for the two tables of the law, and in fitting the precious stones in the ephod; and Solomon in cutting the stones for the building of the temple; and is so hard that it cannot be broken by iron: and as hard is naturally the heart of man, and which becomes more so by sinning, and obstinate persisting in it, that nothing can remove the hardness of it but the powerful and efficacious grace of God: as hard as the adamant is, it is to be softened by the blood of a goat, as naturalists says (h); so the blood of Christ sprinkled on the heart, and a sense of forgiveness of sin by it, will soften the hardest heart: lest they should hear the law, and the words which the Lord of hosts hath seat in his Spirit by the former prophets; the words of reproof, admonition, caution, and exhortation, which Jeremiah and others were sent to deliver to them, under the influence of the Spirit of God: therefore came a great wrath from the Lord of hosts; which brought the Chaldeans upon them, who carried them captive into Babylon.

We have done with the visions, but not with the revelations of this book; the prophet sees no more such signs as he had seen, but still "the word of the Lord came to him." In this chapter we have, I. A case of conscience proposed to the prophet by the children of the captivity concerning fasting, whether they should continue their solemn fasts which they had religiously observed during the seventy years of their captivity (Zac 7:1-3). II. The answer to this question, which is given in this and the next chapter; and this answer was given not all at once, but by piece-meal, and, it should seem, at several times, for here are four distinct discourses which have all of them reference to this case, each of them prefaced with "the word of the Lord came," (Zac 7:4-8 and Zac 8:1, Zac 8:18). The method of them is very observable. In this chapter, 1. The prophet sharply reproves them for the mismanagements of their fasts (Zac 7:4-7). 2. He exhorts them to reform their lives, which would be the best way of fasting, and to take heed of those sins which brought those judgments upon them which they kept these fasts in memory of (Zac 7:8-14). And then in the next chapter, having searched the wound, he binds it up, and heals it, with gracious assurances of great mercy God had yet in store for them, by which he would turn their fasts into feasts.

7:10 Widows, orphans, foreigners, and the poor often did not have access to the legal protection afforded the average citizen (cp. Deut 24:14, 17-18). Fasting and social justice should go hand in hand (see Isa 58:6-7).
