'Weak' in the Bible

Be gracious to me, Lord, for I am weak;heal me, Lord, for my bones are shaking;

I think of God; I groan;I meditate; my spirit becomes weak.Selah

Do not hold past sins against us;let Your compassion come to us quickly,for we have become weak.

My knees are weak from fasting,and my body is emaciated.

Although my spirit is weak within me,You know my way.Along this path I travelthey have hidden a trap for me.

Listen to my cry,for I am very weak.Rescue me from those who pursue me,for they are too strong for me.

My spirit is weak within me;my heart is overcome with dismay.
