Jerome : (Verse 16.) When I send the most destructive arrows of famine (the Vulgate adds 'against them'), which will be deadly, and I will send them to destroy you, and I will gather famine upon you, and I will break the staff (or rod) of bread. Famine and pestilence, and the most terrible beasts, and whatever other evils we endure in this world, it is clear that they come because of our sins. Thus, that famine which is mentioned in the book of Ruth (Ruth 1) and in the book of Kings under Elijah (3 Kings 17), when the heavens were closed for three years and six months, and under Elisha (4 Kings 6), whose incredible scarcity was compensated by sudden abundance by God's judgment, was sent. Not only was this done in Jerusalem at that time, but it also happens in our Jerusalem, where, because of the magnitude of sins, hunger is first sent to hear the word of God. Then hunger is followed by death, so that those who have not heard may experience: Taste and see that the Lord is sweet (Psalms 33:9), and afterwards let us feel: The death of sinners is most bitter (Psalms 22). We have already spoken about the firmament and the staff of bread (above, IV). — Commentary on Ezekiel
