'Refusing' in the Bible

and if thou art refusing to send away, lo, I am smiting all thy border with frogs;

“As soon as I leave you,” Moses said, “I will appeal to the Lord, and tomorrow the swarms of flies will depart from Pharaoh, his officials, and his people. But Pharaoh must not act deceptively again by refusing to let the people go and sacrifice to the Lord.”

for, if thou art refusing to send away, and art still keeping hold upon them,

for if thou art refusing to send My people away, lo, I am bringing in to-morrow the locust into thy border,
