The Biblical god is all that is bad if the deeds attributed to it had any credibility, so therefore it would be surprising if it didn't expect humans to put it before anything else in their lives.
Compare and contrast:
""I am the LORD your God, who brought you out of the land of Egypt, out of the house of bondage.
"You shall have no other gods before me""
Exodus 20: 2,3
"He has showed you, O man, what is good;
and what does the LORD require of you
but to do justice, and to love kindness,
and to walk humbly with your God?"
Micah 6:8
"When you spread forth your hands,
I will hide my eyes from you;
even though you make many prayers,
I will not listen;
your hands are full of blood
Wash yourselves; make yourselves clean;
remove the evil of your doings
from before my eyes;
cease to do evil,
learn to do good;
seek justice,
correct oppression;
defend the fatherless,
plead for the widow."
Isaiah 1: 15-17
