In several instances in the Old Testament, fasting is linked with intercessory prayer. David prayed and fasted over his sick child (2 Samuel 12:16), weeping before the Lord in earnest intercession (vv. 21-22).
Katika matukio kadhaa katika Agano la Kale, kufunga kunahusishwa na maombi ya kuombea. Daudi aliomba na kufunga juu ya mtoto wake mgonjwa (2 Samweli 12:16), akilia kwa bidii mbele za Bwana katika maombezi (vv. 21-22).
