SB 9.7.15

iti putrānurāgeṇa
 sneha-yantrita-cetasā
kālaṁ vañcayatā taṁ tam
 ukto devas tam aikṣata
Word for word: 
iti — in this way; putra-anurāgeṇa — because of affection for the son; sneha-yantrita-cetasā — his mind being controlled by such affection; kālam — time; vañcayatā — cheating; tam — unto him; tam — that; uktaḥ — said; devaḥ — the demigod Varuṇa; tam — unto him, Hariścandra; aikṣata — waited for the fulfillment of his promise.
Translation: 
Hariścandra was certainly very much attached to his son. Because of this affection, he asked the demigod Varuṇa to wait. Thus Varuṇa waited and waited for the time to come.
