Allah(ﷺ) is God’s name in Islam and Arabic. Unlike the noun “God” which has its plural form, Allah(ﷺ) does not. Allah(ﷺ) has many beautiful names by which He can be referred. Allah(ﷺ) says in the Quran,

‘Say, “Call upon Allah or call upon the Most Merciful. Whichever [name] you call – to Him belong the best names.” And do not recite [too] loudly in your prayer or [too] quietly but seek between that an [intermediate] way.’

Quran 17:110

The name Allah(ﷺ) is also found in the Bible. This can be noticed in the video:

What is-  Eli, Eli, lama sabachthani? Mt 27:46

About the ninth hour Jesus cried out with a loud voice, saying, “Eli, Eli, lama sabachthani ?” that is, “my god, my god, why have you forsaken me ?”

Mt 27:46

Says a lot on Gods Names, and His first Personal Name is Elohim, though that is kind of hebrew plural for El and Eloah and the same Elahh in my above ref link, and all these were derived from elah or alah!

Excerpt-

“… II. Absolute or Personal Names of God in the Old Testament:

1. ‘Elohim:
The first form of the Divine name in the Bible is ‘Elohim, ordinarily translated “God”… ….It is one of a group of kindred words, to which belong also ‘El and ‘Eloah…..

(2) The derivation is quite uncertain. Gesenius, Ewald and others find its origin in ‘ul, “to be strong,” from which also are derived ‘ayil, “ram,” and ‘elah, “terebinth”; it is then an expanded plural form of ‘el; others trace it to ‘alah, “to terrify,” and the singular form is found in the infrequent ‘eloah, which occurs chiefly in poetical books; BDB inclines to the derivation from ‘alah, “to be strong,” as the root of the three forms, ‘El, `Eloah and ‘Elohim, …”
