'Bow' in the Bible

He fleeth from an iron weapon, Pass through him doth a bow of brass.

My honour is fresh with me, And my bow in my hand is renewed.

When they bow down in dens -- Abide in a thicket for a covert?

They bow down, Their young ones they bring forth safely, Their pangs they cast forth.

The son of the bow doth not cause him to flee, Turned by him into stubble are stones of the sling.
