Several things are explicit in the verse: (1) the timing is framed as “in that day,” (2) the thanks is directed to Yahweh, (3) the anger was real and personal (“with me”), and (4) the turning away of anger results in comfort. Beyond that, readers infer what kind of “day” is in view and what kind of “comfort” is meant.

Where interpretation differs (only where needed)

What “in that day” refers to. Some read it as a specific future historical deliverance in Isaiah’s storyline (a turning point after crisis), and Isaiah 12 as a song responding to that restored situation. Others read it as pointing beyond any near-term event to a later, larger act of deliverance that Isaiah has been describing, so the “day” becomes a marker for a decisive era of rescue.

Who “me” represents. Some take the “me” as an individual worshiper’s voice. Others see the speaker as a representative “I,” standing for the people as a whole, so that personal language gives a shared, communal confession.

How to picture anger “turning away” and “comfort.” Some understand this mainly as a change in outward circumstances that signals restored favor and security. Others emphasize inner reassurance and renewed relationship; the outward change may be included, but the key idea is relational peace.

Why the disagreement exists

The verse is short and poetic, and it uses signals (“in that day,” first-person “me,” and broad words like “comfort”) that depend on nearby context for precision. Since the immediate line does not specify the event, the group/individual scope, or the form of comfort, interpreters fill those gaps by tracing the flow of the surrounding chapters and by comparing similar “in that day” uses elsewhere in Isaiah.

What this passage clearly contributes

Isaiah 12:1 contributes a basic theological movement: divine anger is not portrayed as Yahweh’s last word. The verse also ties the turning away of anger to Yahweh’s active “comfort,” not merely to the absence of anger. And it presents gratitude as the fitting speech for a restored relationship—language meant to be said aloud when the crisis of divine displeasure has given way to care and reassurance (Isaiah 12:1).
