A version that would also The holiday of "Ata Honananu" (for those who are bothered by it) will be between the days of the strike/rest and the days of the action (without Sheshet).

Sorry, the link in the comment above doesn't work, but you can search Google for the Eretz Israel version > for the Wikitext that appears in the results > for the evening prayer for Shabbat.
