Deuteronomy 17:20

לְבִלְתִּ֤י רוּם־לְבָבוֹ֙ מֵֽאֶחָ֔יו וּלְבִלְתִּ֛י ס֥וּר מִן־הַמִּצְוָ֖ה יָמִ֣ין וּשְׂמֹ֑אול לְמַעַן֩ יַאֲרִ֨יךְ יָמִ֧ים עַל־מַמְלַכְתּ֛וֹ ה֥וּא וּבָנָ֖יו בְּקֶ֥רֶב יִשְׂרָאֵֽל׃ ס

ἵνα μὴ ὑψωθῇ ἡ καρδία αὐτοῦ ἀπὸ τῶν ἀδελφῶν αὐτοῦ, ἵνα μὴ παραβῇ ἀπὸ τῶν ἐντολῶν δεξιὰ ἢ ἀριστερά, ὅπως ἂν μακροχρονίσῃ ἐπὶ τῆς ἀρχῆς αὐτοῦ αὐτὸς καὶ οἱ υἱοὶ αὐτοῦ ἐν τοῖς υἱοῖς Ἰσραήλ.

Para que no se eleve su corazón sobre sus hermanos, ni se aparte del mandamiento á diestra ni á siniestra: á fin que prolongue sus días en su reino, él y sus hijos, en medio de Israel.

Then his heart will not be exalted above his countrymen, and he will not turn aside from the commandment, to the right or to the left, in order that he and his sons may reign many years over his kingdom in Israel.
