11:18-23 The prophet Jeremiah tells much concerning himself, the times he lived in being very troublesome. Those of his own city plotted how they might cause his death. They thought to end his days, but he outlived most of his enemies; they thought to blast his memory, but it lives to this day, and will be blessed while time lasts. God knows all the secret designs of his and his people's enemies, and can, when he pleases, make them known. God's justice is a terror to the wicked, but a comfort to the godly. When we are wronged, we have a God to commit our cause to, and it is our duty to commit it to him. We should also look well to our own spirits, that we are not overcome with evil, but that by patient continuance in praying for our enemies, and in kindness to them, we may overcome evil with good.
