In denouncing the unfaithful kings of Judah, Jeremiah plays on the word for shepherd. The English word is based on the word sheep, but the Hebrew word is based on the a verb meaning to tend, pasture, and feed. Jeremiah tells the kings that they has not attended to the flock, so now the LORD will attend to them. Exile and death in a foreign land, and loss of a dynasty will be the result. The LORD will raise up a new king in Judah, a righteous branch.
LORD, thank you for caring for your flock, and sending Jesus, your righteous Branch.
