שָׁמַ֣יִם לָ֭רוּם וָאָ֣רֶץ לָעֹ֑מֶק וְלֵ֥ב מְ֝לָכִ֗ים אֵ֣ין חֵֽקֶר׃
天之高，地之深，君王的心也是如此，都無法測透。
Ein Yaakov (Glick Edition)
Further said Raba b. Mechasia in the name of R. Chama b. Guria who said in the name of Rab: "If all the seas were ink; all the reeds were producing pens; the expanse if heaven were sheets of parchment, and all the children of men were scribes, yet it would not suffice to write the devices of political government." What is the Biblical passage [that refers to this]? R. Mesharshia said (Pr. 25, 3.) As the height of the heavens, and the depth of the earth, so is the heart of kings unsearchable.
