The most powerful argument against the JEDP theory is the Bible itself. Jesus, in Mark 12:26, said, “Now about the dead rising—have you not read in the book of Moses, in the account of the bush, how God said to him, 'I am the God of Abraham, the God of Isaac, and the God of Jacob'?” Therefore, Jesus says plainly that Moses wrote the account of the burning bush in Exodus 3:1-3. Luke, in Acts 3:22, comments on a passage in Deuteronomy 18:15 and credits Moses as being the author of that passage.
Yesu, katika Marko 12:26, alisema, "Na kwa habari ya watu ya kwamba wafufuliwa hamjasoma katika kitabu cha Musa; Sura ya Kijiti, jinsi Mungu alivyomweambia, akisema, Mimi ni Mungu wa Ibrahimu, na Mungu wa Isaka, a Mungu wa Yakobo?" Kwa hiyo, Yesu anasema wazi kwamba Musa aliandika akaunti ya kichaka kilichokuwa kinawaka moto katika Kutoka 3:1-3. Luka, katika Matendo 3:22, anasunguzia juu ya kifungu katika Kumbukumbu la Torati 18:15 na kumtambua Musa kama mwandishi wa kifungu hicho. Paulo, katika Warumi 10:5, anazungumzia utakatifu Musa anauelezea katika Mambo ya Walawi 18:5.
