'Burdensome' in the Bible

But the king said to Absalom, “No, my son, we should not all go, for we will be a burden to you.” Although Absalom [strongly] urged David, still he would not go, but he gave him his blessing.

And in that day I will make Jerusalem a heavy stone for all the peoples; all who lift it will be severely injured. And all the nations of the earth will come and be gathered against it.

And when I was with you and ran short [financially], I did not burden any of you; for what I needed was fully supplied by the brothers (Silas and Timothy) who came from Macedonia (the church at Philippi). So I kept myself from being a burden to you in any way, and will continue to do so.

For the [true] love of God is this: that we habitually keep His commandments and remain focused on His precepts. And His commandments and His precepts are not difficult [to obey].
