He actually wants both their weapon and divinity, but he knows he can't have their weapon if they don't give it up. This is the divine realm, so they can put their divine weapons into their inventory before their death, so the best he can get if he forces them is their divinity and the armor on their body, which will need to be removed before they can put it into their inventory.
This is why he is hoping to lull them with false promises. He thought it would work since no divine weapon should be worth 5,000 divinity at this stage. At most, their weapon should be something fancy because it changes shape. That shouldn't be enough for them to risk half their total divinity. But they didn't fall for it.
Instead, they killed another three of his gods. This made him frown. However, their refusal to comply didn't discourage the god.
He said, "Fine. Take the hard way. I'll accompany you on this difficult path that you have chosen."
