Which lines in this excerpt from shakespeare's romeo and juliet show that lord capulet thinks juliet is too young to get married?

paris: of honourable reckoning are you both;
and pity 'tis you lived at odds so long.
but now, my lord, what say you to my suit?

capulet: but saying o'er what i have said before:
my child is yet a stranger in the world;
she hath not seen the change of fourteen years,
let two more summers wither in their pride,
ere we may think her ripe to be a bride.

paris: younger than she are happy mothers made.

capulet: and too soon marr'd are those so early made.
the earth hath swallow'd all my hopes but she,
she is the hopeful lady of my earth:
but woo her, gentle paris, get her heart,
my will to her consent is but a part;
an she agree, within her scope of choice
lies my consent and fair according voice.
this night i hold an old accustom'd feast,
whereto i have invited many a guest,
such as i love; and you, among the store,
one more, most welcome, makes my number more.
