The Milwaukee Brewers, ordered by their manager four months ago to go out and enjoy themselves, completed that assignment today by winning the American League pennant with a 4-3 victory over the California Angels. The victory, achieved on Cecil Cooper's bases-loaded, two-run single with two out in the seventh inning, catapulted the Brewers into their first World Series in their 13-year history. The Brewers, who won the Eastern Division title on the last day of the season by beating the Baltimore Orioles, also became the first team in the 14-year history of championship series play to win the three-of-fivegame series after losing the first two games. ''I had all the confidence in the world we were going to come back and win the thing,'' said Harvey Kuenn, who replaced Bob (Buck) Rodgers as the manager June 2 with the Brewers tied for fifth place and seven games out of first. It was at his first meeting with the players that Kuenn told them to go out and have fun.

A Yeshiva University professor has cracked a 2,000-year-old linguistic puzzle and discovered portions of Jewish psalms addressed to Egyptian gods in a previously untranslatable Egyptian manuscript. The scholar, Dr. Richard C. Steiner of the university's Bernard Revel Graduate School, said the discovery might provide the earliest concrete evidence that the psalms were used for worship outside of Jerusalem, as well as a rare and early example of an ancient religion borrowing another's rituals. Dr. Steiner, a linguist, also said the translation would be of immense help in understanding how Aramaic, a Semitic language with some parallels to ancient Hebrew that was the lingua franca of the ancient Near East for centuries, was spoken. He and Dr. Charles F. Nims, professor emeritus at the University of Chicago's Oriental Institute, will report on their analysis of the so-called ''mystery papyrus'' in a forthcoming issue of the Journal of the American Oriental Society.

The chief negotiators for the National Football League players and owners agreed today to seek Federal help to end the impasse that has wiped out the National Football League schedule for the last three weekends. In a secretly called meeting at the Rye Town Hilton Hotel, they agreed to ask Kay McMurray, the director of the Federal Mediation and Conciliation Service in Washington, to help them find a mediator satisfactory to both sides. The agreement to have a mediator join the negotiations was the first sign of progress in the strike, which becomes three weeks old Monday. The first indication that this meeting was unlike many of those that proceeded it was the way it ended. Standing before newsmen, smiling and joking after the four-hour session, were Jack Donlan, the executive director of the National Football League Management Council; Ed Garvey, executive director of the N.F.L. Players Association; Gene Upshaw, president of the Players Association, and Sargent Karch, a lawyer for the Management Council.

Israel announced today that its troops would not withdraw from Lebanon until the Beirut Government signed a security agreement with Israel and all Israeli prisoners in Syrian and Palestinian hands were returned. The decision came in a four-and-a-half-hour Cabinet meeting designed to set forth Israel's bargaining position in the coming negotiations for a mutual Syrian and Israeli departure from Lebanon. The talks with Syria are being held through American mediation. The Cabinet repeated its earlier demand that the Palestine Liberation Organization leave the country first, before the mutual withdrawal begins.

A buying panic erupted in the credit markets last week, bringing spectacular price gains and yield declines and leading Wall Street professionals to forecast even lower interest rates in the weeks ahead. The Federal Reserve, they say in substance, will encourage a further decline in rates because of its basic motivation to shore up the nation's faltering economy. Their forecast was strengthened Saturday when Paul A. Volcker, chairman of the Federal Reserve Board, said in a speech to the Business Council meeting in Hot Springs, Va., that the Fed would tend to ignore erratic data on the money supply in the weeks ahead. In effect, Mr. Volcker said, the Fed realizes that technical factors - especially the recycling of ''All Savers'' deposit money through the banking system - would distort money supply figures and that these figures thus should not be followed too closely in trying to influence interest rates by managing the money supply.
