This appears to be Moore's translation. A variety of translations is given in the The Gospel of Thomas Collection:
Stephen Patterson and Marvin Meyer: Jesus said, "Know what is in front of your face, and what is hidden from you will be disclosed to you. For there is nothing hidden that will not be revealed. [And there is nothing buried that will not be raised.]"
Thomas O. Lambdin: Jesus said, "Recognize what is in your sight, and that which is hidden from you will become plain to you. For there is nothing hidden which will not become manifest."
Marvin Meyer: Yeshua said, / Know what is in front of your face / and what is hidden from you will be disclosed. / There is nothing hidden that will not be revealed.
Stevan Davies: Jesus said, "Recognize what is right in front of you, and that which is hidden from you will be revealed to you. Nothing hidden will fail to be displayed. [And there is nothing that is buried that will not be raised.]
Stephen J. Patterson and James M. Robinson: Jesus says: / (1) "Come to know what is in front of you, and that which is hidden from you will become clear to you. / (2) For there is nothing hidden that will not become manifest."
