to be missing: absent from a group, a count, or a supply that ought to be complete
This word almost always turns up inside a denial. Something has been counted, and the report comes back that nothing and nobody is absent: not one item of the plunder David recovered, not one of his men who crossed the Jordan, not one star in the night sky. The force of the word lies in the completeness it guarantees, so it belongs to the language of a roll call rather than of vague shortage.
That gives it two directions of use. Most often it looks at a group or a total and finds it whole. But it can also look at something that ought to be present in a community and find it gone, as when honesty goes missing from public life and there is no justice left. In that use what is absent is not an object but a quality, and English usually reaches for "fails" instead of "is missing".
One passage turns the word around and makes people the ones who could have caused a shortage: Solomon's officers supplied his table month by month and let nothing be lacking. The picture is the same, only seen from the side of whoever is responsible for the supply.
The ordinary Hebrew word for lacking (חָסֵר) starts from the person who feels the need. This word starts from the list.
