'Private' in the Bible

But when you make your prayer, go into your private room, and, shutting the door, say a prayer to your Father in secret, and your Father, who sees in secret, will give you your reward.

And if your brother does wrong to you, go, make clear to him his error between you and him in private: if he gives ear to you, you have got your brother back again.

Not looking everyone to his private good, but keeping in mind the things of others.
