God is reminding the Jewish people of how He had miraculously broken off the oppressive state they had endured by the Egyptians.   How He had lifted the heavy yoke from their neck of subjugation, submission, and servitude…which then empowered them to stand in an upright posture, with heads held high.  God had broken off the yoke of slavery and set the Jewish people free.   And just as God liberated them…Jesus has come to free us from the bondage of sin.  For it tells us in Galatians 5:1, ” It is for freedom that Christ has set us free.  Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery.”  When Jesus comes into our lives,  the bonds of sin are broken…the yoke of guilt and shame are lifted…and we too are then able to walk free with our heads held high.
