'Acknowledging' in the Bible

Also [you shall observe] the Feast of Harvest (Weeks, Pentecost, or First Fruits), acknowledging the first fruits of your labor, of what you sow in the field. And [third] the Feast of Ingathering (Booths or Tabernacles) at the end of the year when you gather in [the fruit of] your labors from the field.

But the king will rejoice in God;Everyone who swears by Him [honoring the true God, acknowledging His authority and majesty] will glory,For the mouths of those who speak lies will be stopped.
