iti ghoratamad bhavat
sannivrttah svayam prabhuh
aste pratiksams taj-janma
iti—thus (thinking in the above-mentioned way); ghora-tamat bhavat—from the most ghastly contemplation of how to kill his sister; sannivrttah—refrained; svayam—personally deliberating; prabhuh—one who was in full knowledge (Kamsa); aste—remained; pratiksan—awaiting the moment; tat-janma—until the birth of Him; hareh—of the Supreme Personality of Godhead, Hari; vaira-anubandha-krt—determined to continue such enmity.
Sukadeva Gosvami said: Deliberating in this way, Kamsa, although determined to continue in enmity toward the Supreme Personality of Godhead, refrained from the vicious killing of his sister. He decided to wait until the Lord was born and then do what was needed.
