Can a woman forget her sucking child, that she should not have compassion on the son of her womb? yea, they may forget, yet will I not forget thee.
Behold, I have graven [tattooed] thee upon the palms of my hands; thy walls [hands] are continually before me.
It seems very unlikely that a mother who has tenderly cared for and nursed her baby could ever forget her child; yet, it is possible. God's Word declares that even though a mother could forget her child, God will NEVER forget us. God's memory is greater than the memory of even the most intimate of human relationships.
In the Bible lands there is a tradition of tattooing the names of those you dearly love on your body. But no one would think of going through the pain of tattooing on the sensitive palms of their hands.
God is Spirit. He does not have physical hands. God uses figures of speech (like tattooing on the palms of His hands) to emphasize things in His Word. Our names are not tattooed on a hidden part of His body. God has declared in this beautiful figure of speech that he has tattooed our names on His palms so that He can hold us in His memory, always right there before His face.
The Word also declares that our "walls" or hands are continually before Him. God has lovingly tattooed our names on His palms even though our own faults and failures are continually before Him. What a wonderful, loving, God we have.
