'Sturdy' in the Bible

And the opening for his head will be in the middle of it; its opening will have an edge all around, the work of a weaver; it will be like the opening of a sturdy garment for it, [so that] it will not be torn.

And the opening of the robe in the middle of it was like the opening of a sturdy garment, [with] an edge for its opening all around so that it would not be torn.

Therefore the Lord, Yahweh of hosts, will send leanness among his sturdy warriors, and a burning like [the] burning of fire will burn under his glory.
