Isaiah 44:1-3

Verses 1-3

וְעַתָּה שְׁמַע יַעֲקֹב עַבְדִּי וְיִשְׂרָאֵל בָּחַרְתִּי בוֹ׃ 

כֹּה־אָמַר יְהוָה עֹשֶׂךָ וְיֹצֶרְךָ מִבֶּטֶן יַעְזְרֶךָּ אַל־תִּירָא עַבְדִּי יַעֲקֹב וִישֻׁרוּן בָּחַרְתִּי בוֹ׃ 

כִּי אֶצָּק־מַיִם עַל־צָמֵא וְנֹזְלִים עַל־יַבָּשָׁה אֶצֹּק רוּחִי עַל־זַרְעֶךָ וּבִרְכָתִי עַל־צֶאֱצָאֶיךָ׃ 

Israel the Chosen
44 “But now listen, O Jacob, my servant,
Israel, whom I have chosen.
2 This is what the LORD says—
he who made you, who formed you in the womb,
and who will help you:
Do not be afraid, O Jacob, my servant,
Jeshurun, whom I have chosen.
3 For I will pour water on the thirsty land,
and streams on the dry ground;
I will pour out my Spirit on your offspring,
and my blessing on your descendants.

In verse 1, what is the use of ב in בוֹ? It appears to be idiomatic "for myself." This could have been said a number of ways.

"Jeshurun" (וִישֻׁרוּן) means "godly one" and is a better nickname for God's people than "Deceiver" Jacob or "Wrestles with God" Israel. Deuteronomy 32-33.

The only other places "Jeshurun" occurs are in Deuteronomy 32:15, 33:5 and 33:26 ("Jeshurun grew fat and kicked," "(the Lord) was king of Jeshurun," and "the God of Jeshurun"). The word Jeshurun means "the upright one," and is a nickname given to Israel by God. We might notice that in all four places where it is used,God is seen as the one who chose Israel, even when the "fat and kicking" chosen one rejected God.

God promises to bless his chosen people, and once again we see the doctrine or teaching of election being painted for us. And again, as with a birth certificate, the teaching doesn't tell us about God's relationship with other people; only our own relationship with God. He will bless us, and pour out his spirit upon us. That happened in a dramatic way on Pentecost, but it also happens to each of us still today, as God's spirit creates faith in our hearts and waters that faith.

In verse 3, "thirsty land" is literally "thirsty ones" (עַל־צָמֵא). John 7:37 ff, Feast of Tabernacles was near the beginning of the rainy season because without any rain, there would be no harvest next year. So the "pouring out" was important symbolically: Showers of blessings.

The curious word צֶאֱצָאֶיךָ "offspring" is more often "leaving, dung." But perhaps the reference is to the fertilizer aspect more than the shameful aspect. At any rate, your blessings will sprout like a Chia Pet.
