'Footed' in the Bible

How are you able to say, I am not unclean, I have not gone after the Baals? see your way in the valley, be clear about what you have done: you are a quick-footed camel twisting her way in and out;

See, I will take them from the north country, and get them from the inmost parts of the earth, and with them the blind and the feeble-footed, the woman with child and her who is in birth-pains together: a very great army, they will come back here.

Let not the quick-footed go in flight, or the man of war get away; on the north, by the river Euphrates, they are slipping and falling.
