Salmos 137:9
And see then also how the Spirit counselleth thee, saying, "Dash the children of Babylon upon the stones while they are young." And well hath the word of prophecy called these passions "children", that it might show thee their powerlessness, and might encourage thee to victory; and it did not say "thy children," that it might not cause thee disgrace, as if such children appeared from thee, but it named them "children of Babylon," that is to say, children who were born of slavery and not of freedom, because the mother which giveth birth to lusts is the slavery which the word of prophecy hath symbolized by Babylon which hath been wasted, and which carrieth off rapaciously like spoil the power of the spiritual man, and plundereth his riches. — 13 Ascetic Discourses, Discourse 11 -- On Abstinence
