Targum Pseudo-Jonathan on Genesis 9:14 explains the rainbow with a detail the plain Hebrew does not supply. When I spread forth My glorious cloud over the earth, the bow shall be seen in the day (time), while the sun is not sunk (or hidden) in a cloud.
Stop and notice what the Targum is teaching you. The rainbow is a meeting of two things — a cloud and a sun. The cloud alone cannot produce it. The sun alone cannot produce it. You need rain behind you and light in front of you. That is why the bow appears while the sun is not hidden. The storm must be real, but so must the light.
This is Jewish theology rendered in weather. The covenant is not that there will be no more clouds. It is that the cloud will not be allowed to swallow the sun. Judgment and mercy are painted into the same sky at the same moment, and together they produce color.
Ancient Jewish tradition teaches that when we see a rainbow we recite a blessing thanking the Holy One who remembers the covenant. Not the one who ended the storm — the one who remembers.
The takeaway the Maggid gathers here: the next time rain and sunshine arrive together in your life, do not be surprised. That is the shape of God's promises. Both at once.
