yatsa, “to bring or go forth or out,” strong’s H3318

The first occurrence.

And the earth brought forth grass, and herb yielding seed after its kind, and the tree yielding fruit, whose seed was in itself, after its kind: and God saw that it was good. Gen 1:12

The primitive root.

Strong’s H3318  יצא  yatsa, a primitive root meaning, “to go out, to go forth.” The 3-letter root is yud + tsadey + aleph.

yud י = the closed hand, thus work, throw, worship
tsadey צ ץ  = the trail, thus a man concealed, journey, chase, hunt
aleph א = the ox head, thus strength, power, leader

The cognate word “excrement” is the key to unlock the parable. The man enclosed (yud, as something done privately) squats down (tsadey, as a man on a trail squats down to conceal himself from the prey), and, by the strength of his core (aleph) causes his excrement to issue forth.
