'Form' in the Bible

Then look, there was {one in the form of a human}; he touched my lips and I opened my mouth and I spoke and I said to the [one] standing {before me}, "My lord, because of the vision my anxieties fell upon me and I [have] not retained [my] strength.

And {he again touched} me, {the one in the form of a human}, and he strengthened me.

And he will set his face to come with the authority of his whole kingdom and will form an agreement; and he will {act}, and the daughter of women he will give to him to destroy it, but [the ploy] will not succeed {and she will not support him}.
