Bare bodkin is the salient point (no pun intended) of this line, so it gets the stresses. This creates a pyrrhic/spondee/iamb/iamb/iamb rhythm. Bodkin at the time meant a sharp instrument, much like an awl, used for punching holes in leather.
The meaning and origin of the expression: Odds bodkins. Odds bodkins. Meaning. God's body. Origin. The phrase sounds entirely suited to Tudor yokels and is a stock in trade of any author wishing for a shortcut to convey a sense of 'Olde Engylande'. A bodkin is a small tool for piecing holes in leather etc. This term borrows the early bodikin version of that word, not for its meaning but just because of the alliteration with body, to make a euphemistic version of the oath God's body. This would otherwise have been unacceptable to a pious audience. That is, odds bodkins is a minced oath.
