"That thou shalt set apart unto the LORD all that openeth the matrix, and every firstling that cometh of a beast which thou hast; the males shall be the LORD'S" (Ex. 13.12).

Here matrix means womb.

I know the word matrix means "something that constitutes the place or point from which something else originates, takes form, or develops:
The Greco-Roman world was the matrix for Western civilization."

But the movie the Matrix has a similar meaning in that the matrix is the place or point from which their perceived existence originates. People were living in the matrix and each person who escaped the matrix and is released is set apart for the Lord like Neo was.

And it is like those the machine world are feeding off of are in the womb, connected up as batteries, to give energy to the machine world which is the Satanic world.
