'Sickly' in the Bible

After them, seven other cows, sickly and thin, came up from the Nile and stood beside those cows along the bank of the Nile.

The sickly, thin cows ate the healthy, well-fed cows. Then Pharaoh woke up.

After them, seven other cows—ugly, very sickly, and thin—came up. I’ve never seen such ugly ones as these in all the land of Egypt.

Those who are sickly you have not strengthened, the diseased you have not healed, the broken you have not bound up, the scattered you have not brought back, nor have you sought for the lost; but with force and with severity you have dominated them.

Even so, every healthy tree bears good fruit, but the unhealthy tree bears bad fruit.

And He could not do a miracle there at all [because of their unbelief] except that He laid His hands on a few sick people and healed them.

For there is no good tree which produces bad fruit, nor, on the other hand, a bad tree which produces good fruit.

For this cause many are weak and sickly among you, and many sleep.
