That same day, they took seven hundred bulls and seven thousand sheep and goats from what they had brought back from Gerar and sacrificed them as offerings to the LORD.
"The army took them from the Amalekites," Saul explained. "They kept the best sheep and cattle, so they could sacrifice them to the LORD your God. But we destroyed everything else."
All the animals were going to be destroyed anyway. That's why the army brought the best sheep and cattle to Gilgal as sacrifices to the LORD your God."
