In chapter 21 several things are happening. David visits a priest settlement with his band of men.
A little time has gone by, and we see David again going downhill spiritually. Here is one of the values of the life of David: we see him one minute with strong faith, and then we see what can happen when he gets worn down. He who in time past had shown such courage when walking with the Lord, is now overcome by fear and resorts to a lie. What a condition to be in! We have all been in this condition. When your faith gets so low, you don't even think it is going to do any good to pray, and so you invent your own remedy, your own way out of the dilemma, even if it means that you have got to stoop to excusing yourself, or lying, on doing something you shouldn't be doing. Let us learn from David: you can walk by faith, and then if you do not watch you can soon be brought very low.
‘And David said unto Ahimelech the priest,’ – so here is another story; there are efforts made to excuse David in this – ‘The king hath commanded me a business, and hath said unto me, Let no man know any thing of the business whereabout I send thee, and what I have commanded thee: and I have appointed my servants to such and such a place.’ People suggest – and it may be so – that David told this story to protect Ahimelech, to give Ahimelech the opportunity to say, ‘He told me he was on a special mission. I didn't know he was on the run.’ Then others say, David had a permanent commission, if necessary, to sort out some diplomatic things with a much smaller party, and to do it secretly and to tell nobody. They say that that is what he is talking about. ‘Don’t you know, Ahimelech, I have a commission to conduct secret missions; I can't tell you what I am doing.’ But it is still a bit of a stretch, in order to cover his being on the run from the king's wrath and murder, to invent this elaborate story. Once again you see signs of David's integrity crumbling after the loss of faith.
Ahimelech shouldn't really have been officiating. He was a descendant of Eli, and God had said that all Eli's sons were disqualified from priesthood, and there was also the prophecy that they would be judged, and the time would come when all the sons of Eli would disappear. If the children of Eli had only got out of the priesthood, or laid down their responsibilities and gone and worked their homesteads like other people, and not attempted to officiate, perhaps the judgement of God would not have been bought upon them. But the house of Eli had to be brought to an end, and they didn't listen. It is interesting that they were still used by God. You could still seek the Lord's will through them. That is often how God works even today. In our churches, we may do things which are wrong and condemned by the Scripture. Various evangelical churches may engage in things like extreme worldliness, which are extremely dishonouring to God. It does not mean that God takes away all their instrumentality and usefulness instantly. They are put under notice, just as somebody might be who is renting a flat and misbehaves; there will be a notice period. If the people of God, or those who claim to be the people of God, disobey the methods of God, they won't necessarily be immediately disposed of by the Lord. This confuses some people. They say, ‘Here is this or that preacher who has become notorious for doing things that are quite unbiblical. Why is it that they still see some fruit, and some usefulness, and their churches have not totally disintegrated or come under judgement? Because there are warnings given, and there is a period of grace, a notice period; and it seems that Ahimelech and all the line of Eli were still being tolerated by the Lord. If they had known what was good for them, they would have retired completely from priestly functions, but actually there was no way they were going to do that, and so a prophet was able to say to Eli, this judgement will happen; it will take place, because God of course knew that they would not give up their office and their functions.
