The first vision Prophet Jeremiah saw at his call was

The first vision that Prophet Jeremiah saw at his call was a vision of a rod of almond. According to the Bible, Jeremiah was a prophet who was called by God to prophesy to the people of Judah. In his first vision, God showed Jeremiah a branch of an almond tree, which symbolized God's readiness to watch over his word and perform it. In the vision, God asked Jeremiah what he saw, and Jeremiah responded that he saw a branch of an almond tree. God then explained the meaning of the vision to Jeremiah, saying that just as the almond tree is the first tree to bloom in the spring, so too God would watch over his word and perform it quickly. The vision of the almond branch was a sign of God's power and faithfulness, and it reassured Jeremiah that God was with him and would give him the strength and courage to fulfill his calling as a prophet. It also served as a reminder to the people of Judah that God was always watching over them and was ready to act on their behalf.
