It sure is different!

For the most part the speeches take the form of prose prayer, even in the exceptional case linked to ritual—the story of David and the census (1 Chr 21:17; cf. 2 Sam 24:17). Instead, intercessors appeal to pathos, logos, and occasionally ethos to persuade YHWH that his plans would subvert his own interests, be inconsistent with his nature or his promise to the patriarchs, or cost him the people whom he loves. The emphasis on divine injustice in many of these speeches stands in sharp contrast to Texts 1-4. The final chapter demonstrates how the biblical presentation of apotropaic intercession reflects a very different understanding of divine-human relations than we see in Texts 1-4.—Forestalling Doom page 147

That sure is different from the other ANE stuff, isn't it? YHWH isn't a god to be controlled by ritual or magic.

And what was true then is just as true now. You can't "claim the promise" and demand that God has to fulfill your (usually selfish) wish—see James 4:3, "You ask and don’t have because you ask with evil intentions, to waste it on your own cravings." (CEB)
