'Loading' in the Bible

So David got up early in the morning and entrusted the flock to someone else who would watch over it. After loading up, he went just as Jesse had instructed him. He arrived at the camp as the army was going out to the battle lines shouting its battle cry.

At that time I saw people in Judah treading wine presses on the Sabbath. They were also bringing in stores of grain and loading them on donkeys, along with wine, grapes, and figs. All kinds of goods were being brought to Jerusalem on the Sabbath day. So I warned them against selling food on that day.

For I have bent Judah as if it were my bow, loading it with Ephraim. I raised up your sons, Zion, against your sons, Greece, wielding you like a mighty warrior's sword."

And it hath come to pass, in that day, I make Jerusalem a burdensome stone to all the peoples, All loading it are completely pressed down, And gathered against it have been all nations of the earth.
