Elohiem can be singular and plural.
In Deut 6:4 it is singular, because God says so:
שמע ישראל י-ה-ו-ה אלהנו י-ה-ו-ה אחד
Hear Israel, Y-H-W-H is our God, Y-H-W-H is ONE.
And you shall love
Y-H-W-H your God with all your heart, and with all your soul, and with all your might.
And these words which I command you this day shall be upon your heart;
and you shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise.
And you shall bind them as a sign upon your hand, and they shall be as frontlets between your eyes.
And you shall write them on the doorposts of your house and on your gates.
Deut 6:4-9
The Jews until this day fulfill this commandment. Every morning they put upon their arm and upon their forehead their phylacteries, (prayer belts) that consist of black straps with black leather cubes, that contain parchment upon which is written this Biblical text that says that God is one. Upon the doorposts of the houses of the religious Jews there are small boxes or containers that also contain parchment upon which is written that God is one. During the morning and evening prayers the above text is recited which says that God is one.
Y-H-W-H, the one and only God who is one.
Beside Him there is no God, no Buddha, no Christ, no David Koresh; NOBODY.
Whoever worships anything or anybody else than
Y-H-W-H is an
IDOL WORSHIPPER.
