'Dedicate' in the Bible

Remember the Sabbath day, to keep it holy:

Be careful to remember the Sabbath day, to keep it holy as the Lord your God has commanded you.

“The officers are to address the army, ‘Has any man built a new house and not dedicated it? Let him leave and return home. Otherwise, he may die in battle and another man dedicate it.

Samuel told them, “If you are returning to the Lord with all your heart, get rid of the foreign gods and the Ashtoreths that are among you, dedicate yourselves to the Lord, and worship only Him. Then He will rescue you from the hand of the Philistines.”

Now I am building a temple for the name of Yahweh my God in order to dedicate it to Him for burning fragrant incense before Him, for displaying the rows of the bread of the Presence continuously, and for sacrificing burnt offerings for the morning and the evening, the Sabbaths and the New Moons, and the appointed festivals of the Lord our God. This is ordained for Israel forever.

It is a trap for anyone to dedicate something rashlyand later to reconsider his vows.
