for when their apostles came to them with all evidence of the truth, they arrogantly exulted in whatever knowledge they [already] possessed: and [so, in the end,] they were overwhelmed by the very thing which they were wont to deride.

For when their apostles came to them with Clear Signs, they exulted in such knowledge (and skill) as they had; but that very (Wrath) at which they were wont to scoff hemmed them in.

And when their messengers brought them clear proofs (of Allah's Sovereignty) they exulted in the knowledge they (themselves) possessed. And that which they were wont to mock befell them.

Then when their messengers came to them with clear arguments, they exulted in what they had with them of knowledge and that at which they used to mock befell them.

And when their messengers came to them with clear proofs, they [merely] rejoiced in what they had of knowledge, but they were enveloped by what they used to ridicule.
