"Je le connais bien et je lui fais confiance."

Translation: I know him well, and I trust him.

[Fred.duo]

first "le" then "lui". Why?

[GraemeSarg]

Because it is "faire confiance à qn" → indirect object.

Alternatively you could say "… et j'ai confiance en lui.". I do not know which is closer to "I trust him" and which is closer to "I have confidence in him".

"Faire confiance à qqn" and "avoir confiance en qqn" are often interchangeable, although "faire confiance" can be a one-time stance while "avoir confiance" is more permanent.

[RicklesXVI]

The audio doesn't sound like the French written sentence. At normal audio speed, the actor says "mais je lui fais confiance" rather than "et je lui fais confiance". I thought I was going crazy!

If this were "I know her well," etc..., Would it be "Je la connais..."?

[GraemeSarg]

Yes.
