List of contradictions:
Could Shem have been Melchizedek (Gen. 14:18)? Jasher 16:11 certainly points us in that direction. It says, "And Adonizedek King of Jerusalem, the same was Shem, whent out with his men to meet Abram and his people, with bread and wine, and they remained together in the valley of Melech." It is an interesting possibility to consider that Abraham and his descendants traveled back and forth to visit Shem and Eber.

Jasher 13:5 says that Abram went to the land of Canaan at the age of 50 then back to Haran and back to Canaan at age 75, Genesis 12:4 states that Abram was 75 when he departed Haran.
Jasher 80:2-51 lists these Plagues; Exodus chapters 7-12
1. Waters into blood (v. 3) / Exodus 7:20
2. Frogs (v. 6) / Exodus 8:6
3. Lice (v. 10) / Exodus 8:17
4. The Lord sent all kinds of beasts into Egypt and destroyed all Egypt ( v.13) / Not in Exodus
5. Fiery serpents, scorpions, mice, weasels, toads (v. 14) / Not in Exodus

Chapter 71:1 of Jasher states that Moses was 18 years old when he left Egypt. He didn't go to Midian but to Cush and becomes king (72:34-36) and is king over Cush for forty years (73:2), then he goes to Midian where Reuel puts him in prison for 10 years because Reuel thinks Moses is wanted by the Cushites. In the book of Acts (7:23-30) Stephen, inspired by the Holy Spirit, stated the Moses was in Egypt for 40 Years before going to Midian for another 40 years.

Jasher 81:3-4 claims that the Israelites sojourned in Egypt for 210 years whereas the Scripture says in Exodus 12:40-41 it was 430 years.

Jasher 81:40-41says that all but Pharaoh perished in the Red Sea. Pharaoh thanks the Lord and the Lord sends an angel who casts him upon the land of Nineveh where Pharaoh reigned for a long time. Scripture (Exodus 14:23 & 28) states that all perished.
