'Heads' in the Bible

‘Also if you bring a grain offering of early ripened things to the Lord, you shall bring fresh heads of grain roasted in the fire, grits of new growth, for the grain offering of your early ripened things.

Then Moses said to Aaron and to his sons Eleazar and Ithamar, “Do not uncover your heads nor tear your clothes, so that you will not die and that He will not become wrathful against all the congregation. But your kinsmen, the whole house of Israel, shall bewail the burning which the Lord has brought about.

You shall not round off the side-growth of your heads nor harm the edges of your beard.

They shall not make any baldness on their heads, nor shave off the edges of their beards, nor make any cuts in their flesh.
