Jerome : (Verse 15.) Like the chick of a swallow, so will I cry out: I will meditate as a dove: My eyes are weakened looking towards the height. Lord, I suffer violence; answer for me: what shall I say or what shall he answer me when he himself has done? LXX: Like a swallow, thus will I cry out; like a dove, thus will I meditate. For my eyes have failed from looking towards the height of heaven to the Lord: who delivers me, took away the pain of my soul, and he himself did it. Death was imminent, and the pain of illness weighing upon me, like a lion, was breaking all the bones of my body; but I, like a swallow and a dove, joined together day and night with weeping and moaning; and from God alone, who was able to help, I waited for assistance, with my eyes lifted up to the heights. And I said to him: I suffer more than my merits require; but even if I have gone astray, I will turn to the better; you answer for me: For it is not of him that wills, nor of him that runs, but of God that shows mercy (Rom. 9:16). And it turns back again into itself: What can I say, or with what can I argue against my Creator? Or what will he answer to me, he who did himself what he wanted? Therefore, whatever he decides must be endured. The word for swallow, or swallow, as translated by the LXX, is written in Hebrew, Sus Agor (), which Aquila interpreted as horse Agor: Theodotius, Sis Agur (); for the middle vocal letter vau, if placed between two Samechs, is read as pig, and is called horse; if yod, it is read as swallow. However, Symmachus translated it as follows: As a swallow enclosed, so will I sing. This word is also found in Jeremiah, where it is written: The kite in the sky knew its time: the turtle-dove, and the swallow, and the stork kept their times (Jeremiah VIII, 7). — Commentary on Isaiah
