King David, 66, a lawyer here for many years who also was a minister in the African Methodist Episcopal Church, died Friday at the University of Maryland Hospital in Baltimore.

Mr. David was known as a colorful and flamboyant figure in Superior Court and its predecessor, the old Court of General Sessions, where he argued a wide variety of cases.

He was a hardworking lawyer who "fought for what he believed in," and was basically a force for good, according to Chief judge Theodore R. Newman Jr., of the D.C. Court of Appeals.

Mr. David was born in Florida and reared in East Orange, N.J. He attended Upsala College there before graduating from Howard University Law School.

Mr. David began a law practice here almost 30 years ago. In addition, he was an associate pastor at Turner Memorial AME Church and preached at other churches here and around the nation.

In a 1962 appearance in D.C. Juvenile Court, he won praise from a judge for his interest in the welfare of a 14-year-old youth he represented.

The youth was arraigned on charges of assault, shoplifting and rifling a parking meter. The judge permitted the youth to go home on probation pending trial but warned him to behave.

Mr. David turned to the youth and repeated the warning. "I'm going to check on you every day myself," he said. Then Mr. David told the youth's mother to report to him every day on the youth's activities.

When the woman, who received public assistance, said she might not be able to afford the calls, David replied: "I'll come to your house myself. Just keep a running log of his activities, and I'll do the rest."

In addition to his wife, Helena, of the home in Washington, he is survived by two sons, Derek and King II, both of Los Angeles, and three sisters, Louise, Wylie and Thersea, all of Newark, N.J.
