what does "I shall not want" mean? [closed]

Consider this part of bible : 23 The Lord is my shepherd; I shall not want. I was wondering the meaning of second sentence, I shall not want. This is not clear to me the reference to the verb want and also the general meaning of the sentence.


"Want" is a synonym of "lack." Saying "I shall not want" is similar to saying "I shall not lack" or "I shall not be in need" or "I shall not be lacking anything."
