Hebrews 4:12

¹⁰ For whoever enters God’s rest also rests from his own work, just as God did from His.

¹¹ Let us, therefore, make every effort to enter that rest, so that no one will fall by following the same pattern of disobedience.

For the word of God is living and active. Sharper than any double-edged sword, it pierces even to dividing soul and spirit, joints and marrow. It judges the thoughts and intentions of the heart.

¹³ Nothing in all creation is hidden from God’s sight; everything is uncovered and exposed before the eyes of Him to whom we must give account.

¹⁴ Therefore, since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold firmly to what we profess.

Do read the surrounding verses too, because the context often says more than a single verse.
