Lehi teaches his son Jacob about Jesus Christ in the next few verses. In verse 7, He will offer himself as a sacrifice for sin. In verse 8, no flesh can dwell in the presence of God, that’s the Holy of Holies. In verse 9, He is the first fruits which belonged to God and had to be brought to the temple under the Law of Moses. Through the sacrifice of the first fruits one could be reconciled with God. Lehi would have known that from his own revelations and also from Isaiah Chapter 53.
"He offers himself to answer the ends of the law unto all those who have a broken heart and a contrite spirit." Those last words are found in the Psalms, and they will also be spoken by Jesus from the darkness of the cloud in 3 Nephi, and unto none else can the ends of the law be answered. "Wherefore, how great the importance to make these things known unto the inhabitants of the earth that they may know that there is no flesh that can dwell in the presence of God save it be through the merits and mercy and grace of the Holy Messiah."
