Which two lines or sets of lines in the poem suggest the preciousness of love? Sonnet 12
by Elizabeth Barrett Browning

Indeed this very love which is my boast,
And which, when rising up from breast to brow,
Doth crown me with a ruby large enow
To draw men's eyes and prove the inner cost,—
This love even, all my worth, to the uttermost,
I should not love withal, unless that thou
Hadst set me an example, shown me how,
When first thine earnest eyes with mine were crossed,
And love called love. And thus, I cannot speak
Of love even, as a good thing of my own:
Thy soul hath snatched up mine all faint and weak,
And placed it by thee on a golden throne,—
And that I love (O soul, we must be meek!)
Is by thee only, whom I love alone.
