Exhibit 23.3
Consent of Independent Registered Public Accounting Firm
The Board of Directors
Zion Oil & Gas, Inc.
We consent to the use of our report dated March 16, 2011, with respect to the balance sheets of Zion Oil & Gas, Inc. (a development stage company) as of December 31, 2010 and 2009, and the related statements of operations, stockholders' equity and cash flows for each of the years in the three year period ended December 31, 2010 and for the period from April 6, 2000 (inception) to December 31, 2010 and with respect to the effectiveness of internal control over financial reporting as of December 31, 2010, incorporated herein by reference and to the reference to our firm under the heading "Experts" in the prospectus. Our report dated March 16, 2011 contains an explanatory paragraph that states that Zion Oil & Gas Inc. is in the development stage and has no operating revenue, limited capital resources and a loss from operations, all of which raise substantial doubt about its ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of that uncertainty.
