Ezekiel 5:3

It is now added: Thou shalt take then a small number, and bind them, (that is, that number, but the number is changed,) viz., those hairs of which the number is small in the skirts of thy clothing It either takes away the confidence which might spring up from a temporary escape, or else it signifies that very few should be safe in the midst of the destruction of the whole people, which came to pass wonderfully. If that is received, the correction is added, that God would give some hope of favor because the people was consumed, yet so that the covenant of God might remain. Hence it was necessary that some relics should be preserved, and they had been reduced like Sodom, unless God had kept for himself a small seed. (Isaiah 1:9; Romans 9:29.) Therefore in this sense the Prophet is ordered to bind and to hide in the skirts of his garment, some part of the hair. Moreover, that part is understood only in the third order, because those who had escaped thought that they had obtained safety by flight, especially when they collected themselves in troops. Afterwards it follows, thou shalt then take from these, and throw it into the midst of the fire, and burn it in the fire Out of these few hairs God wishes another part to be burnt and consumed; by which words he signifies, even where only a small portion remains, yet it must be consumed in like manner, or at least that many out of these few will be rejected. And indeed those who seemed to have happily escaped and to have survived safely, were soon after cut off by various slaughters, or pined away by degrees as if they had perished by a slow contagion. But since it pleased him to remember his promise, we gather that a few of the people survived through God’s wonderful mercy: for because he was mindful of his covenant, he wished some part to be preserved, and therefore that correction was interposed, that the Prophet should bind under his skirts a small number. Yet from that remnant, God again snatched away another part, and cast it into the fire. If the filth of the remainder was such, that it was necessary to purge it, and cast part of it into the fire, what must be thought of the whole people, that is, of the dregs themselves? For the portion which the Prophet bound in his skirts was clearly the flower of the people: if there was any integrity, it ought to be seen there.
