'Nation's' in the Bible

From the sole of the foot even to the headThere is nothing healthy in the nation’s body,Only bruises, welts, and raw wounds,Not pressed out or bandaged,Nor softened with oil [as a remedy].

“Your [nation’s] riches and your treasuresI will give as plunder without price [to the Babylonians],Because of all your sinsAnd within all your territories.

For this nation’s heart has grown hard,And with their ears they hardly hear,And they have [tightly] closed their eyes,Otherwise they would see with their eyes,And hear with their ears,And understand with their heart, and turn [to Me]And I would heal them [spiritually].’
