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
wantand 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.”
