(Pro 28:27 KJV) He that giveth unto the poor shall not lack: but he that hideth his eyes shall have many a curse.
As I compare translations, before looking at the Hebrew, I find that I like the implication of the KJV better than the NASB. It isn’t that the more contemporary translation is wrong, it is just more in the tradition of the KJV and using somewhat archaic language. In modern times “want” (4270) has become the mantra of the selfish generation. How many times have you seen cartoons with the theme of “I want, I want”? If you remember the saying, “Waste not, want not” you come closer to the “lack” of the KJV.
I have come close to being in want. Once in seminary I was down to my last can of tomato soup before the Lord made a grocery run. During our first pregnancy we traveled across country and arrived in California with no job and ten dollars in our pockets. But in spite of the fact that I might have wanted more, I have never lacked what I needed.
So? Need something to be thankful for? You should not have to look very far.
