In Jer 13:6, the LORD later commands Jeremiah to retrieve the loincloth—the direct narrative continuation of the purchase in 13:2.

Isaiah 20:2 shows Isaiah obeying God's command to walk naked and barefoot as a sign, just as Jeremiah obeyed the sash command.

Hosea 1:2 contains the same kind of symbolic command (marry a prostitute) that Jeremiah obeys here, showing a pattern of prophetic actions.

Hosea 1:3 records Hosea's obedience to take Gomer; Jeremiah's purchase of the sash is a direct parallel of obeying a symbolic command.
