They are treaty stipulations

Once we recognize the presence of a stock treaty format in the Old Testament, the literary role of Israel’s legal sayings can be identified: they comprise the stipulations of the covenant agreement. That is, the lists of legal collections familiar in the ancient world have been reused in a second genre, covenant/treaty, where they serve as stipulations. This important observation gives us further information by which to understand how to interpret the sayings (as treaty stipulation, not legislation). Most importantly, it indicates that though Yahweh is Israel’s God, the covenant features him as Israel’s suzerain king.—Walton and Walton, The Lost World of the Torah, 48
