the burying of a dead body, and the grave or ground where the body is laid
This word is built straight off the verb "to bury" (קָבַר), and it keeps both halves of that idea inside one word: the burying itself, and the place where the burying is done. So a writer can say a king was laid "in his burial" and mean his tomb, or say a man had "no burial" and mean the act was never performed for him. English has to pick between "grave" and "burial" in every verse. Hebrew does not have to pick.
Most often it names one person's resting place, doing much the same work as the commoner word for a grave (קֶבֶר), and the person's name is what identifies the spot: the pillar over Rachel's grave, the grave of Moses that nobody can find, a king's own grave in the city of David. A few passages widen it to ground the dead share, which is why Jacob asks to be carried out of Egypt and laid in the burial place his fathers already hold, and why Ezekiel pictures whole armies ranged around a national burial ground far down in the pit.
The remaining use is the heaviest. In the world of these texts a body left out in the open was the last and worst disgrace, and this word carries that weight three times over:
- the man who lives a hundred years, fathers a hundred children, and still gets no burial
- the king of Babylon who will not be joined with his own royal line in the tomb
- the king of Judah who will be dragged out and dumped past the city gates the way a dead donkey is
Read "burial" in those verses as a funeral service and the sentence goes soft. The question being asked is whether the body gets into the ground at all.
