When bowing the knee

“Oh come, let us worship and bow down; let us kneel before the Lord, our Maker!” (Psalm 85:6 ESV) 

Bowing the knee: Bowing and kneeling have long been associated with worship and reverence. The Hebrew word for “worship” actually means “bow down.” 

No one but God must be worshipped

“You shall not bow down to them or serve them, for I the Lord your God am a jealous God, visiting the iniquity of the fathers on the children to the third and the fourth generation of those who hate me.” (Exo. 20:5 ESV)

“You shall not make idols for yourselves or erect an image or pillar, and you shall not set up a figured stone in your land to bow down to it, for I am the Lord your God.” (Lev. 26:1 ESV)

“For they provoked him to anger with their high places; they moved him to jealousy with their idols.” (Psalm 78:58 ESV)

Every knee will bow before Jesus

“It is written: “‘As surely as I live,’ says the Lord, ‘every knee will bow before me; every tongue will acknowledge God.'” (Rom. 14:11 NIV)

“But I, through the abundance of your steadfast love, will enter your house. I will bow down toward your holy temple in the fear of you.” (Psalm 5:7 ESV)

Therefore…

“Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father. (Phil 2:9-11 ESV)

“You alone are the LORD. You have made the heavens, The heaven of heavens with all their host, The earth and all that is on it, The seas and all that is in them. You give life to all of them And the heavenly host bows down before You.” (Neh. 9:6 NASB)
