The very same sample of "Ike's Rap II" was used in four tracks at about the same time in the mid-1990s: Hell Is Around The Corner by Tricky, Glory Box by Portishead, Jorge da Capadócia and Salve both by Brazilian rap group Racionais MC's.
The album's title derives from Stax executive Dino Woodward's nickname for Hayes, which he bestowed upon the musician after comparing the effects of his music on black audiences to the leadership of the biblical figure Moses. The then deeply Christian Hayes shied away from the nickname, finding it "sacrilegious", [ WE MUST KEEP ONE VERY IMPORTANT REALIZATION...ISAAC HAYES...IS NOTHING LIKE THE REAL MOSES...THE MOSES IN THE BIBLE WAS CALLED BY GOD FOR A WAY DIFFERENT REASON...AGAIN...ISAAC HAYES IS (NOTHING-LIKE-THE-MOSES) IN THE BIBLE.  although journalist Chester Higgins popularized the "Black Moses" nickname in an article he wrote on Hayes for Jet. Hayes came to see "Black Moses" as a symbol of black pride:
"Black men could finally stand up and be men because here's Black Moses; he's the epitome of black masculinity. Chains that once represented bondage and slavery now can be a sign of power and strength and sexuality and virility"
Larry Shaw, head of marketing and publicity at Stax, came up with the idea to name Hayes' LP Black Moses. He also devised, with the assistance of Bar-Kays member Ron Gordon, a gatefold album cover design which unfolded into a poster-sized image of Hayes, dressed in biblical-inspired attire as "Black Moses".
