Kabbalah zu Jirmejahu 4:6

Hashem behaved similarly toward Abraham, as it is written, "that the Elohim did test Abraham" (Gen. 22:1). What is meant by "test (Heb. נִסָּה)?" It means the raising of the banner (Heb. נֵס), as it is written, "lift up a standard" (Isaiah 62:10), and "set up the standard" (Jer. 4:6). He raised his standard over the whole world. And for this, the Holy One, blessed be He, raised the banner of Abraham before everybody's eyes, as it is written, "Did test Abraham." Thus the Holy One, blessed be He, in order to lift the standard of the righteous, tries them, so they will lift up their heads throughout the world.
