The Vishnu Purana: Book IV: Chapter XIII

Agreeably to the advice of Audhaka the elder, the Yádavas sent a mission, headed by Keśava, Ugrasena, and Balabhadra, to assure Akrúra that no notice would be taken of any irregularity committed by him; and having satisfied him that he was in no danger, they brought him back to Dwáraká. Immediately on his arrival, in consequence of the properties of the jewel, the plague, dearth, famine, and every other calamity and portent, ceased. Krishńa, observing this, reflected 15 that the descent of Akrúra from Gándiní and Śwaphalka was a cause wholly disproportionate to such an effect, and that some more powerful influence must be exerted to arrest pestilence and famine. "Of a surety," said he to himself, "the great Syamantaka jewel is in his keeping, for such I have heard are amongst its properties. This Akrúra too has been lately celebrating sacrifice after sacrifice; his own means are insufficient for such expenses; it is beyond a doubt that he has the jewel." Having come to this conclusion, he called a meeting of all the Yádavas at his house, under the pretext of some festive celebration. When they were all seated, and the. purport of their assembling had been explained, and the business accomplished, Krishńa entered into conversation with Akrúra, and, after laughing and joking, said to him, "Kinsman, you are a very prince in your liberality; but we know very well that the precious jewel which was stolen by Sudhanwan was delivered by him to you, and is now in your possession, to the great benefit of this kingdom. So let it remain; we all derive advantage from its virtues.
