I think it means the follower, who wants God to lead them through the good and
bad things and choices of the world, which involves things that can tempt them
to do bad, things that make efforts to get them to do bad, asks God for the
strength to resist those efforts.
The Adam and Eve tree story involves God making a test of fidelity--is it to
God or for self against God--not tempting them to make the wrong choice, which
would be the case if His effort was just to have them to make the wrong choice.
Likewise with Abraham, God tests Abraham's faith. The idea isn't that God
tempts Abraham to do bad but tests how good Araham was at being abidant to God.
Abraham began to carry out what God told him to do so God rewarded him for good
It reminds me of another use of the word "tempt"--the JWs leaders stance
against the mainstream view of Jesus is that it's wrong because the Devil tempts
Jesus three times and God can't be tempted. But "tempt" can be the effort to
get someone to do something or the person's own urge to do it. It doesn't have
to include both the effort to make another do something and the other's consent.
Someone can tempt another but whether or not they're successful is another
thing--that's still the choice of the other's free will.
The Devil doesn't seem to have been sure of Jesus' identity and made the
effort to have Jesus forsake God three times, which could happen with either the
JWs leaders' or the mainstream idea of Jesus' identity, so it doesn't support
the JWs leaders' stance.
God can't be tempted doesn't mean God can't react at all, such as to faith,
etc., just that people can't get God to do their will against His will--His
choices are up to Him. The story in Ex.17 doesn't alter that. Moses is given
as concerned that the followers, who were out of water, shouldn't try to tempt
God to go against His will. Moses stays true to God though he's worried the
followers may turn on him. God supplies them with water, not that it's given
that they got him to do it against His will as if He wanted them to die of
thirst. He'd promised them a land to go to.
