'Heavy' in the Bible

For day and night Your hand [of displeasure] was heavy upon me;My energy (vitality, strength) was drained away as with the burning heat of summer. Selah.

For my iniquities have gone over my head [like the waves of a flood];As a heavy burden they weigh too much for me.

You brought us into the net;You laid a heavy burden [of servitude] on us.
