2.35.26

ayaṃ tu puruṣo bālaḥ śiśupālo na budhyate |
sarvatra sarvadā kṛṣṇaṃ tasmādevaṃ prabhāṣate || 26 ||

This Sisupala is a mere boy and hence he knoweth not Krishna, and ever and everywhere speaketh of Krishna thus. This ruler of Chedi will never see virtue in that light in which one that is desirous of acquiring high merit will see it. Who is there among the old and the young or among these illustrious lords of earth that doth not regard Krishna as deserving of worship or that doth not worship Krishna? If Sisupala regardeth this worship as undeserved, it behoveth him to do what is proper in this matter.'"
