v1: Referring back to chapter 36, the fourth year of Jehoiakim. The promises of God were given to Baruch years before they fled into Egypt.
v2: Words specifically addressed to Baruch. The Lord knows those who are His, and he knows our specific circumstances, and speaks into them.
v3: Baruch had shared Jeremiah’s faithfulness, and had shared in his suffering. Their suffering actually surpassed that of the people because they cared deeply for them.
v4: The word of the Lord was to overthrow and uproot, see 1.10. Baruch should not trust in those things around him.
v5: Baruch must not seek great things for himself. God, however, promised him life and security; he would not be slaughtered with the rest of the people. We find our satisfaction in God, and in His promises for our lives.
Amidst the chaos and carnage of the Babylonian invasion, God’s hand was on an individual. We find hope in the same God would knows those who trust in Him.
