dnd 5th – How many skills and languages ​​does a cleric in the field of half-elven knowledge begin?

I'm starting a new character sheet for a noble half-elf cleric (domain of knowledge), and I'm just asking about skills and languages.

In how many things would I be competent and how many languages ​​should I know? In addition, is it the skill bonus, does it also apply to skills I master well?

I'm not super new to the game, but the character sheets are always those where I get lost.
