In that day the Lord will take away the bravery of their tinkling ornaments about their feet, and their cauls, and their round tires like the moon,

Wesley's Notes

3:18 Cauls - It is agreed by all, that this and several words that follow, were ornaments used in those times. And it is of no concern, exactly to understand the nature and differences of them. The moon - There were in ancient times, and at this day there are some ornaments worn, which carry a manifest resemblance to the moon or half moon.

King James Translators' Notes

cauls: or, networks

Jamieson-Fausset-Brown Bible Commentary

18. bravery-the finery.

tinkling-(See Isa 3:16).

cauls-network for the head. Or else, from an Arabic root, "little suns," answering to the "tires" or neck-ornaments, "like the moon" (Jud 8:21). The chumarah or crescent is also worn in front of the headdress in West Asia.

Matthew Henry's Concise Commentary

3:16-26 The prophet reproves and warns the daughters of Zion of the sufferings coming upon them. Let them know that God notices the folly and vanity of proud women, even of their dress. The punishments threatened answered the sin. Loathsome diseases often are the just punishment of pride. It is not material to ask what sort of ornaments they wore; many of these things, if they had not been in fashion, would have been ridiculed then as now. Their fashions differed much from those of our times, but human nature is the same. Wasting time and money, to the neglect of piety, charity, and even of justice, displease the Lord. Many professors at the present day, seem to think there is no harm in worldly finery; but were it not a great evil, would the Holy Spirit have taught the prophet to expose it so fully? The Jews being overcome, Jerusalem would be levelled with the ground; which is represented under the idea of a desolate female seated upon the earth. And when the Romans had destroyed Jerusalem, they struck a medal, on which was represented a woman sitting on the ground in a posture of grief. If sin be harboured within the walls, lamentation and mourning are near the gates.
