Line 8 And she steal love's sweet bait from fearful hooks
simply, imho, one of the most beautiful verses ever
Line 2 . . . and find thy centre out
playing on syntax, Romeo seems to hint at his personal center now being out of himself -- in Juliet
Line 3 . . . and Juliet is the sun
O sole mio. . .
Line 34 Deny thy father and refuse thy name
A request like those made by Christ in the Gospels (Luke 14.26). See also Psalm 45.10, a bridal song, though the words are spoken to "her," the princess, in that case.
Lines 92-3 . . . at lovers' perjuries
They say Jove laughs
"they" who? An unusual role for the father of the gods and illegitimate children
Line 144 Thy purpose marriage, send me word to-morrow
tomorrow! 14 y.o. Juliet wastes even less time than her father will
Line 163 With repetition of my Romeo's name
possibly with reference to the echo: Romeo... meo... meo... (i.e. mio, "mine own," in Medieval Italian)
