If someone comes into money, property, or a title, they receive it as a result of the death of a relation.

She came into a bit of money when her grandfather died. 祖父死后，她继承了一小笔钱。

If a particular emotion or quality comes into a situation, it influences that situation.

She married for money - love didn't come into it. 她结婚是为了钱——并不是因为爱情。
