Numbers 22:7

With magic chas in their hands. All types of magic charms, so that he could not say, “My tools are not with me.” Another interpretation. The elders of Midian took up this mystical omen: They said, “If he comes with us this time, there is something to him; but if he rebuffs us, it is useless.” This is why, when he said to them, “Spend the night here,” they said, “It is hopeless.” They left him there and departed, as it is said, “the Moavite chieftains stayed with Bil’am,” but the elders of Midian departed.

And the elders of Moab and of Midian went, with the price of divinations sealed up in their hands, and came to Bileam, and told him the words of Balak.

וקסמים בידו, they brought along charms of their own to forestall Bileam saying that he did not have any of these charms handy. We read in Ezekiel 21, 27-28: “in his right hand the קסם, sorcery, indicated Jerusalem, to appoint commanders to urge on to murder. But it was for them as a vain divination, קסם שוא, etc.”

וקסמים בידם, the instruments by means of which to perform sorcery.. Bileam’s specific expertise in such sorcery was to calculate precisely when certain constellations would be favourable to what he planned to achieve. He is described as a sorcerer when his death his reported in Joshua 13,22.

וילכו זקני מואב, “The elders of Moav went forth, etc.” The Talmud in tractate Sanhedrin folio 105, tells us that there never had been peaceful relations between Moav and Midian before, but now that both felt threatened, they became like dogs when afraid of wolves that threaten them, and they acted in unison.

וקסמים בידם, “and they had brought instruments .of divination with them.” They brought money with them to pay Bileam for employing divinations with which to curse the Israelites. This is the way the Jerusalem Talmud translated our verse. An alternate interpretation is that seeing that Balak himself was no novice in that art, he sent along samples of what he used when practicing divination.
