I"m sure you've heard this before about how the Bible interprets the Bible.
KJV "Is.5:22 Woe unto them that are mighty to drink wine, and men of strength to mingle strong drink."
"Is.5:23 Which justify the wicked for reward, and take away the righteousness of the righteous from him."
"Is.5:24 -----because they have cast away the law of the LORD of hosts, and despised the word of the Holy One of Israel."
Verses 23 and 24 explain 22.
Is. 5:22 has nothing to do with drinking wine or strong drink. It has everything to do with departing from the truth and following our own ways.
Here are some other verses as examples.
KJV "Is. 51:21 Therefore hear now this, thou afflicted, and drunken, but not with wine."
"Jer. 51:7 Babylon hath been a golden cup in the LORD'S hand, that made all the earth drunken: the nations have drunken of her wine; therefore the nations are mad." (This is saying that we are following the sins of Babylon.)
"Is. 29:9 Stay yourselves, and wonder; cry ye out, and cry: they are drunken, but not with wine; they stagger, but not with strong drink."
"Is. 19:14 The LORD hath mingled a perverse spirit in the midst thereof: and they have caused Egypt to err in every work thereof, as a drunken man staggereth in his vomit."
Our LORD is using the example of drunkenness to help us to comprehend how fallen we are. We are drunken in the ways of the world. Our very culture is what we're drinking in. All the bling and excess has caused us to stagger in our walk. Our world has blinded us to the truth. So we have departed from God to follow our own ways. In the KJV Is. 5:22, it's our leaders, the people we look up to for guidance that are most guilty. They lead and we follow.
NIV "Is. 5:22 Woe to those who are heroes at drinking wine and champions at mixing drinks."
My interpretation of this verse as (guys at a bar having a good time) though an attempt at lighthearted humor, is about right. The NIV people missed it altogether and wrote and meant it as actually drinking. I'm not wrong since that's exactly how the NIV readers have interpreted it. You can see that in this thread. Another sad part about it is since the authors got the first part wrong, the readers are left with interpreting the following verses as a consequence of being drunk. It's totally misunderstood.
The NIV has a pattern of doing this. They did the same thing in Prov. 23:30-35 and totally ruined it.
