(4.) It is also a private particular mourning. There shall be not only a mourning of the land, by its representatives in a general assembly (as Judg. ii. 5, when the place was called Bochim—A place of weepers), but it shall spread itself into all corners of the land: Every family apart shall mourn (v. 12), all the families that remain, v. 14. All have contributed to the guilt, and therefore all shall share in the grief. Note, The exercises of devotion should be performed by private families among themselves, besides their joining in public assemblies for religious worship. National fasts must be observed, not only in our synagogues, but in our houses. In the mourning here foretold the wives mourn apart by themselves, in their own apartment, as Esther and her maids. And some think it intimates their denying themselves the use even of lawful delights in a time of general humiliation 1 Cor. vii. 5. Four several families are here specified as examples to others in this mourning:—[1.] Two of them are royal families: the house of David, in Solomon, and the house of Nathan, another son of David, brother to Solomon, from whom Zerubbabel descended, as appears by Christ's genealogy, Luke iii. 27-31. The house of David, particularly that of Nathan, which is now the chief branch of that house, shall go before in this good work. The greatest princes must not think themselves exempted from the law of repentance, but rather obliged most solemnly to express it, for the exciting of others, as Hezekiah humbled himself (2 Chron. xxxii. 26), the princes and the king (2 Chron. xii. 6), and the king of Nineveh, Jonah iii. 6. [2.] Two of them are sacred families (v. 13), the family of the house of Levi, which was God's tribe, and in it particularly the family of Shimei, which was a branch of the tribe of Levi (1 Chron. vi. 17), and probably some of the descendants of that family were now of note for preachers to the people or ministers to the altar. As the princes must mourn for the sins of the magistracy, so must the priests for the iniquity of the holy things. In times of general tribulation and humiliation the Lord's ministers are concerned to weep between the porch and the altar (Joel ii. 17), and not only there, but in their houses apart; for in what families should godliness, both in the form and in the power of it, be found, if not in ministers' families?
