ते तु तूर्णमुपव्रज्य देवक्या गर्भजन्म तत् ।
आचख्युर्भोजराजाय यदुद्विग्नः प्रतीक्षते ॥ २ ॥
te-all the watchmen; tu-indeed; turnam-very quickly; upavrajya-going before (the King); devakyah-of Devaki; garbha-janma-the deliverance from the womb; tat-that (child); acakhyuh-submitted; bhoja-rajaya-unto the King of the Bhojas, Kamsa; yat-of whom; udvignah-with great anxiety; pratiksate-was waiting (for the child's birth).
Kamsa was very anxiously waiting because of the prophecy that the eighth child of Devaki would kill him. This time, naturally, he was awake and waiting, and when the watchmen approached him, he immediately took action to kill the child.
