'Deaths' in the Bible

Zebulun was a people that jeopardized their lives to the deaths; Naphtali also, on the high places of the field.

They shall die grievous deaths: they shall not be lamented, neither shall they be buried; they shall be as dung on the surface of the ground; and they shall be consumed by the sword, and by famine; and their dead bodies shall be food for the birds of the sky, and for the animals of the earth.

Are they servants of Christ? (I speak as one beside himself) I am more so; in labors more abundantly, in prisons more abundantly, in stripes above measure, in deaths often.
