Baruch was a secretary and scribe to the prophet Jeremiah. He lived precisely during the time of Jerusalem’s demise when the Temple was destroyed and the Jews were taken into exile and slavery.
Baruch Chapter 2 is an extended prayer to God by Baruch for deliverance
verses 11-12 “And now, LORD, God of Israel, You who led Your people out of the land of Egypt with Your mighty Hand, with signs and wonders and great might, and with Your upraised Arm, so that You have made for Yourself a Name till the present day: we have sinned, been impious, and violated, O LORD, our God, all Your statutes.”
verses 14-15 “Hear, O LORD, our prayer of supplication, and deliver us for Your own sake: grant us favor in the presence of our captors, that the whole earth may know that You are the LORD, our God, and that Israel and his descendants bear Your Name.”
verse 26 “And You reduced the house which bears Your Name to what it is today, for the wickedness of the kingdom of Israel and the kingdom of Judah.”
Baruch recalls God’s promises in verses 28-32 This was Your warning through Your servant Moses, the day You ordered him to write down Your law in the presence of the Israelites: If you do not heed My Voice, surely this great and numerous throng will dwindle away among the nations to which I will scatter them. For I know they will not heed Me, because they are a stiff-necked people. But in the land of their captivity they shall have a change of heart; they shall know that I, the LORD, am their God. I will give them hearts, and heedful ears; and they shall praise Me in the land of their captivity , and shall invoke My Name.
Baruch 3:5-7 Remember at this time not the misdeeds of out fathers, but Your own Hand and Name: for You are the LORD our God; and You, O LORD, we will praise! For this, You put into our hearts the fear of You: that we may call upon Your Name, and praise You in our captivity, when we have removed from our hearts all the wickedness of our fathers who sinned against You.
The LORD shows His forgiveness in the next entry of His Holy Name.
Baruch 5: 1-2 Jerusalem, take off your robe of mourning and misery; put on the splendor of glory from God forever: wrapped in the cloak of justice from God, bear on your head the miter that displays the glory of the eternal Name.
