Nectar of Devotion 21:

A person whose word of honor is never broken is called truthful. Kṛṣṇa once promised Kuntī, the mother of the Pāṇḍavas, that He would bring her five sons back from the Battlefield of Kurukṣetra. After the battle was finished, when all the Pāṇḍavas had come home, Kuntī praised Kṛṣṇa because His promise was so nicely fulfilled. She said, "Even the sunshine may one day become cool and the moonshine one day become hot, but still Your promise will not fail." Similarly, when Kṛṣṇa, along with Bhīma and Arjuna, went to challenge Jarāsandha, He plainly told Jarāsandha that He was the eternal Kṛṣṇa, present along with two of the Pāṇḍavas. The story is that both Kṛṣṇa and the Pāṇḍavas—in this case Bhīma and Arjuna—were kṣatriyas (warrior-kings). Jarāsandha was also a kṣatriya and was very charitable toward the brāhmaṇas. Thus Kṛṣṇa, who had planned to fight with Jarāsandha, went to him with Bhīma and Arjuna in the dress of brāhmaṇas. Jarāsandha, being very charitable toward the brāhmaṇas, asked them what they wanted, and they expressed their desire to fight with him. Then Kṛṣṇa, dressed as a brāhmaṇa, declared Himself to be the same Kṛṣṇa who was the King's eternal enemy.
