President Biden will nominate former Treasury Secretary Jacob J. Lew as his next ambassador to Israel. Mr. Lew has served in some of the government’s most important posts under two Democratic administrations, in the process earning him many admirers across the aisle.

He ran the Treasury Department for President Barack Obama, was also Mr. Obama’s White House chief of staff, deputy secretary of state, and director of the Office of Management and Budget. Mr. Lew first served in the budget director post under President Bill Clinton, presiding over the last federal government surplus.

He will succeed Thomas R. Nides, another former deputy secretary of state, who stepped down over the summer to return home to his family.

Mr. Lew is an Orthodox Jew. While in public office, he observed Shabbat as much as he could, and made a point of walking to the White House whenever he had to work on a Saturday.
