With respect to Gideon, we find that: "In his days the Jewish people were in distress. The Holy One, Blessed be He, sought a person who would find merit in them. When He found Gideon to be meritorious, because he found merit in them, an angel immediately appeared to him, as it says: "And the angel of G-d appeared to him and said to him, 'Go with this power, with the power of the merit you have found in my children.'"

Further, since Torah "is not in heaven," this ruling issued by the earthly courts "obligates," so to speak, and affords a unique privilege to, the heavenly courts. And so it will be confirmed!

Consequently, the [current] "siege of the Babylonian..."
