Justification by Faith is hidden in the OT, there's a veil that covers it from plain sight. Christ would later come and pull back that veil, and the apostle Paul would completely remove it.
The Biblical introduction of Justification by Faith is found in Gen. 15:6,
"And he (Abraham) believed in the Lord; and he counted it to him for righteousness."
Abraham was saved the same way we are in the New Covenant, Justification by Faith, not by any works, as the apostle Paul so directly pointed out in his epistles. Abraham proved his faith by his works. The righteousness he received for eternal life came solely by faith.
We also know that the faith Abraham exercised was in the coming Messiah, Jesus Christ, although Abraham didn't know His name. Christ Himself tells us that Abraham was very much aware of His coming.
John 8:56
"Your father Abraham rejoiced to see my day: and he saw it, and was glad."
For the OT saints righteousness was freely given by God through faith in the sacrifice of an innocent animal shedding its Blood on the alter, representing Christ on the Cross freely offering Himself, shedding His Blood as the atonement for man's sin.
Lev. 17:11
"For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul."
The great apostle Paul completely removed this OT veil and gave us in detail the meaning of Justification by Faith in his epistles, which is the meaning of the Cross of Christ, which makes up the New Covenant in the Blood of Jesus Christ.
