“his soul.” “His soul,” in this context the word “soul” refers more to the depths of the person, what is in his heart. This person, for reasons unstated in the text, is not satisfied with what he has.

“no burial.” In the biblical world this would almost be inexplicable since it was a major responsibility for children to bury their parents (cp. Gen. 50:5; Matt. 8:21). No one could conceivably have 100 children but not be properly buried unless they made themselves so repulsive that they were rejected by literally everyone. A burial showed that a person was honored and respected, and in the Bible people were left unburied as a sign of disrespect and contempt, and their dead bodies were usually eaten by animals and birds (see commentary on Jer. 14:16).
