וַֽיַּעֲל֞וּ עַד־נַ֣חַל אֶשְׁכּ֗וֹל וַיִּרְאוּ֙ אֶת־הָאָ֔רֶץ וַיָּנִ֕יאוּ אֶת־לֵ֖ב בְּנֵ֣י יִשְׂרָאֵ֑ל לְבִלְתִּי־בֹא֙ אֶל־הָאָ֔רֶץ אֲשֶׁר־נָתַ֥ן לָהֶ֖ם יְהוָֽה׃
For when they went up unto the valley of Eshcol, and saw the land, they turned away the heart of the children of Israel, that they should not go into the land which the LORD had given them.
Targum Jonathan on Numbers
they went up to the brook of Ethkela, and saw the land, but enfeebled the will of Israel's heart, that they would not enter into the land which the Lord had given to them.
