'Acquainted' in the Bible

“I will betroth you to Me in stability and in faithfulness.Then you will know (recognize, appreciate) the Lord [and respond with loving faithfulness].

“So let us know and become personally acquainted with Him; let us press on to know and understand fully the [greatness of the] Lord [to honor, heed, and deeply cherish Him].His appearing is prepared and is as certain as the dawn,And He will come to us [in salvation] like the [heavy] rain,Like the spring rain watering the earth.”
