'Says' in the Bible

Now a man of God came to Eli and said to him: "Thus says Yahweh: 'Did I not clearly reveal myself to the house of your ancestor when they were in Egypt under the house of Pharaoh?

But he said to him, "Look, a man of God [is] in this town, and the man [is] honored. All that he says certainly comes true. So then let us go there; perhaps he will tell us about our journey on which we have gone."

and he said to the {Israelites}, "Thus says Yahweh the God of Israel: 'I brought Israel up from Egypt, and I delivered you from the hand of the Egyptians and from the hand of all the kingdoms that [were] oppressing you.'

If you will fear Yahweh, and serve him, and listen to his voice, and not be rebellious against {what Yahweh says}, and both you and the king who rules over you will [follow] after Yahweh your God, [all will be well].

But, if you do not listen to the voice of Yahweh, and you rebel against {what Yahweh says}, then the hand of Yahweh will be against you [as it was] against your ancestors.

Thus says Yahweh of hosts: 'I have observed what Amalek did to Israel, {how he opposed him} when he went up from Egypt.

If he says 'Good,' [it will mean] peace for your servant; but if he [is] very angry, know that {he has decided to do me harm}.

Just as the ancient proverb says, 'From the wicked, wickedness goes out,' but my hand will not be against you!
