"Leave" in the line "The sooner you can leave" and "go" in the line "The sooner you can go" are both sung with a melisma (A G), giving a sense of movement.
"Rest" in the line "Take care of yourself; get plenty of rest" is sung with a melisma (A G in one vocal part and D B in the harmony), giving a sense of amount (for "plenty").
"Lies" in the line "Yes, for telling all those lies" is also sung with a melisma (A B), giving a sense of amount (for "all"). While Dylan sings this with a melisma, too, his articulation is different.
