There are exceptions, including students and people attending the wedding of a sibling, child, or grandchild.
Israelis and foreigners who qualify for an exception to enter Israel must go into home quarantine for 14 days through at least June 30. Exceptions to the 14 day quarantine are available with a positive COVID-19, negative COVID-19, and antibody test if you otherwise qualify for entry.
Israel plans to reopen in phases, with citizens from countries with low morbidity to be allowed in first. But the date when the reopening will happen has been pushed back several times and seems likely to be pushed off as Israel is experiencing an increase of new coronavirus cases as the country reopens.
