'Course' in the Bible

And as John was finishing his course [of ministry], he kept saying, ‘What or who do you think that I am? I am not He [the Christ]; but be aware, One is coming after me whose sandals I am not worthy to untie [even as His slave]!’

So setting sail from Troas, we ran a direct course to Samothrace, and the next day [went on] to Neapolis;

But I do not consider my life as something of value or dear to me, so that I may [with joy] finish my course and the ministry which I received from the Lord Jesus, to testify faithfully of the good news of God’s [precious, undeserved] grace [which makes us free of the guilt of sin and grants us eternal life].

Then fearing that we might run aground somewhere on the rocks, they dropped four anchors from the stern [to slow the ship] and kept wishing for daybreak to come.
