Attaching into a wire somewhere along the way is usually not a good idea. I say this for several reasons. You may think you know what the wire is, but you may be wrong. Instead of the wire being a simple power wire you may find a switch loop, or portion of a three way, or something entirely different. Even if you are sure what the wire is, there usually is not enough slack in the wire to properly add a junction box, which is required.

It is much better to grab power from an existing junction box. To do so, the junction box must have constant power, not switched power, unles you want your new light switched by the same switch.

Grab power, neutral and ground from the junction box. Usually this involves adding to existing wire nut connections, but you may very well have to add pigtails and wirenuts, depending on what is already in the box. Power will be the black wire, the neutral will be white and the ground will be bare.

Run your new wire to the switch and then to the light. At the switch you will have two cables, an incoming from the existing junction box and an outgoing to the new fixture. Connect the white wires together and then to nothing else. Connect the bare ground wires together and also connect them to the green screw on the switch and to the junction box, if it is metal. Connect each black wire to one of the non-green screw terminals on the switch.

At the new fixture connect the wires up one to one. The new fixture should have a black wire, a white wire and a bare or green wire.
