Behold, days come, saith Jehovah, that I will sow the house of Israel and the house of Judah [with] the seed of man and the seed of beast.
Behold, days come, saith Jehovah, that I will sow the house of Israel and the house of Judah [with] the seed of man and the seed of beast.
Jeremiah 31:25 For I have satiated the weary soul, and every languishing soul have I replenished.
Jeremiah 31:26 Upon this I awaked, and beheld; and my sleep was sweet unto me.
Jeremiah 31:27 Behold, days come, saith Jehovah, that I will sow the house of Israel and the house of Judah [with] the seed of man and the seed of beast.
Jeremiah 31:28 And it shall come to pass, as I have watched over them, to pluck up, and to break down, and to overthrow, and to destroy, and to afflict; so will I watch over them to build, and to plant, saith Jehovah.
Jeremiah 31:29 In those days they shall say no more, The fathers have eaten sour grapes, and the children's teeth are set on edge:
The verse centers on "behold", "days", "come", "saith", "jehovah", "house", and "israel". It is saying that the verse draws attention to "behold" and "days", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 26's "Upon this I awaked and beheld and..." into verse 28's "And it shall come to pass as...", so "behold" and "days" belong inside that flow. In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "behold" and "days" with trust shaped by these words, not by a vague optimism outside the passage.
