'Feebleness' in the Bible

From the end of the land unto Thee I call, In the feebleness of my heart, Into a rock higher than I Thou dost lead me.

From the sound of the stamping of the hoofs of his mighty ones, From the rushing of his chariot, the noise of his wheels, Fathers have not turned unto sons, From feebleness of hands,

In the feebleness within me of my soul Jehovah I have remembered, And come in unto Thee doth my prayer, Unto Thy holy temple.
