וַיֹּ֤אמֶר אַחְאָב֙ אֶל־עֹ֣בַדְיָ֔הוּ לֵ֤ךְ בָּאָ֙רֶץ֙ אֶל־כָּל־מַעְיְנֵ֣י הַמַּ֔יִם וְאֶ֖ל כָּל־הַנְּחָלִ֑ים אוּלַ֣י ׀ נִמְצָ֣א חָצִ֗יר וּנְחַיֶּה֙ ס֣וּס וָפֶ֔רֶד וְל֥וֹא נַכְרִ֖ית מֵהַבְּהֵמָֽה׃
Y dijo Achâb á Abdías: Ve por el país á todas las fuentes de aguas, y á todos los arroyos; que acaso hallaremos grama con que conservemos la vida á los caballos y á las acémilas, para que no nos quedemos sin bestias.
Ramban
A LAND OF BROOKS OF WATER. The meaning thereof is that it is like a watered garden,77Isaiah 58:11. and it is not necessary to irrigate it by foot as the land of Egypt, as it will yet be stated,78Further, 11:10. for it drinketh water as the rain of heaven cometh down.79Ibid., Verse 11. Now he explained [here] that fountains and depths, come out in deep valleys and mountains,80Verse 7 before us. and from there the brooks flow in the Land, the purport of the verse being “fountains and the fountains of the depths, ” like: when the ‘fountains of the deep’ showed their might;81Proverbs 8:28. the fountains of the great deep.82Genesis 7:11. The reason [for referring to both sources: fountains, and fountains of the deep] is that there are some fountains that flow from the very moisture of the mountains which has been absorbed by them from the rains, or from the clouds that ascend upon them, these being called “fountains” [or “springs”] as it is said, unto all the springs of water,83I Kings 18:5. the flint [He turned] into a fountain of waters.84Psalms 114:8. There are other kinds of fountains which come forth from the interior of the depth, these being called “deep waters” that is to say, the fountains of the depths. The verse is thus stating that both [kinds of fountains] come out in deep valleys and mountains.
Rashi
In what do you trust It is written (I Kings 18:5): “He trusted in the Lord God of Israel,” and it is also written there: (verse 7) “and he rebelled against the king of Assyria.” Therefore, he asked, “In what do you trust” that you have rebelled against me?
