The Old Testament reading order follows the Hebrew Old Testament book order which is divided into the Law, Prophets, and Writings (or Psalms; see Luke 24:44) except for Psalms which would precede Job, but are being read each Sunday.
"If you abide in My word, then you are truly disciples of Mine; and you shall know the truth, and the truth shall make you free." // John 8:31,32 //
