Hosea 3:1

Some think that this chapter refers to Judah, the two tribes, as the adulteress the prophet married (Hos 1:3) represented the ten tribes; for this was not to be divorced, as the ten tribes were, but to be left desolate for a long time, and then to return, as the two tribes did. But these are called the children of Israel, which was the ten tribes, and therefore it is more probable that of them this parable, as well as that before, is to be understood. Go, and repeat it, says God to the prophet; Go yet again. Note, For the conviction and reduction of sinners it is necessary that precept be upon precept, and line upon line. If they will not believe one sign, try another, Exo 4:8, Exo 4:9. Now, I. In this parable we may observe, 1. God's goodness and Israel's badness strangely serving for a foil to each other, Hos 3:1. Israel is as a woman beloved of her friend, either of him that has married her or of him that only courts her, and yet an adulteress; such is the case between God and Israel. We say of those whose affection is mutual that there is no love lost between them; but here we find a great deal of the love even of God himself lost and thrown away upon an unworthy ungrateful people.
