The troubles of my heart are enlarged,.... His enemies being increased, which troubled him; the floods of ungodly men made him afraid; the waters of affliction were come into his soul, and spread themselves, and threatened to overwhelm him: or it may be rendered, as by some, "troubles have enlarged my heart" (h); made him wiser, increased his knowledge and experience; see Psa 119:67; but the former seems better to agree with what follows; O bring thou me out of my distresses; or "straits" (i); for the enlargement of his troubles was the straitening of his heart; and therefore he applies to the Lord to bring him out of his afflicted circumstances, in which he was penned up, as in a strait place, on every side, and which were such that he could not free himself from; but he knew that God could deliver him.
