Name Ariel used in magical formulas of Grand Grimoire, along with three of the divine names. We know that Ariel is the name of an angel. However, the Grand Grimoire indicates it like it is the name of God:
"It is for the honor, glory and power of your name, O ADONAY, ELOHIM, ARIEL and JEHOVA".
The name Ariel comes from Ari and El names. Ari - The Lion, El - God. In the Bible the name Ariel is one of the names of the saint Jerusalem.
But here is the third meaning: homiletic surname of The Lord (A Dictionary of the Targumim, the Talmud Babli and Yerushalmi, and the Midraschic Literature).
