How many planes do two intersecting lines define?

A straight line, which is not limited by anything and is freely in space, has an unlimited number of planes that can pass through it.
Two straight lines that have a common point of intersection, which are intersecting, lie in the same plane.
If we consider these two straight lines as straight lines not connected to each other, then each of them will have a huge number of planes through which the original straight lines can pass, but only one plane through which both straight lines will pass simultaneously.
