'Reed' in the Bible

So the Lord cut off Israel’s head and tail,palm branch and reed in a single day.

sends couriers by sea,in reed vessels on the waters.Go, swift messengers,to a nation tall and smooth-skinned,to a people feared far and near,a powerful nation with a strange language,whose land is divided by rivers.

The channels will stink;they will dwindle, and Egypt’s canals will be parched.Reed and rush will die.

No head or tail, palm or reed,will be able to do anything for Egypt.

Look, you are trusting in Egypt, that splintered reed of a staff that will enter and pierce the hand of anyone who leans on it. This is how Pharaoh king of Egypt is to all who trust in him.

He will not break a bruised reed,and He will not put out a smoldering wick;He will faithfully bring justice.

Will the fast I choose be like this:A day for a person to deny himself,to bow his head like a reed,and to spread out sackcloth and ashes?Will you call this a fastand a day acceptable to the Lord?
