David Jehoahaz Abraham (ダビデ・ヨアズ・アブラヒム Dabide Yoazu Aburahimu) was the leader of the Magicians from Alma Torran and the first Senator in the Orthodox's "Council of Elders". He is the father of Solomon. He is the magi of Sinbad.
David is a tall man, with dark skin. He is commonly seen wearing white robes, and hoop earings. Despite his age David has an appearance of a man in his 30's or 40's. This is due to him using magic to maintain his young age. David also bears a large number of similarities in terms of appearance to that of Sinbad, with whom he has a mysterious connection.
After David was blessed with magic from Ill Ilah, he displays an immense curiosity as he questions why he and the humans were given magic and what was a magician. He later realizes his role in life to surpass God.  Throughout his life, he experimented and used magic to manipulate the lesser species on Alma Torran as he viewed them as stepping stones for him to surpass God.
David wrote a prophetic book after his son Solomon was born. It highlights his views on the world, himself, his son, other magicians, stretching his lifespan, how the creation of the 'gunud' and 'agenda' are just pieces towards his grand mission, and finding the true singularity that will allow him to surpass god.
David was the leader of The Orthodox Church, and the main antagonist.
It is revealed by Alibaba that David is alive and has fused with Ill Ilah. He is also somehow connected to Sinbad. When Sinbad has fallen to Ugo, David takes this chance to reveal himself as he emerges from the Black Rukh that was separated from Sinbad's Rukh. His attempt to take over the Sacred Palace fails as Ugo defeats him and places him into a lower-order world which is seen in a fish tank.  David stated that he had become the guardian of the Sacred Palace.
A flashback of David is shown, he questions what magic is, what a magician is and why god chose him. Back in the present David is shown to have come to a realisation of what his duty is, believing it to be complete before correcting himself and saying that it's just the beginning. David goes on to talk about how magicians are the sages of the king and that a king leads the world and not god. A silhouette of Sinbad is shown, telling David to take his hand and that he will show him a world he couldn't of imagined. David proceeds to pull Sinbad from the great flow before referring to him as his king. As Ugo is having a mental breakdown, David puts him under an illusion. After David does this, Sinbad refers to David as his magi saying that's what he expected of him. 
David is revealed to be a magic genius who has theorized and created many Magic Tools and Magics when he was in Alma Torran, like the magic that enslaves the creatures of Alma Torran, Gunud, and a complex barrier.
David possessed one of the 72 Divine Staves. The wand had the appearance similar to a weighted scale. David has created a form of magic that allows him and anyone who touches his wand, along with those around him to enter a different dimension. Despite not all of his powers and abilities being shown, Solomon himself said that there is no magician more powerful than David. Even Solomon says his own abilities and magic skills are insignificant compared to his father's. David's staff was unique as it served as a key to the dimension where Ill Illah was.
- Borg: This is said to be the proof of a Magician. It is a defensive ability. It blocks out attacks with evil intentions. It also blocks out all physical attacks and magical attacks to some degree. Its strength, however, depends on the person.
While David cannot "see" the future, he can naturally see any kind of phenomena that belongs to the future. This is possible because David devotes himself to observing the paths in the world, and he is able to understand the rules and interactions of such paths.
David originally used Sinbad as a vessel to live within, he did this by resonating with the black rukh inside of Sinbad. He would occasionally talk with Sinbad, teaching him about the magic tools in Alma Torran. Sinbad eventually stopped hearing his voice. After entering the Sacred Palace, David becomes the Magi of Sinbad.
David and Solomon have a strained relationship. While Solomon wonders why David is his father, David acknowledges that he never thought of Solomon as his beloved child.
