Is Infant Baptism Biblical?

"And they brought young children to him, that he should touch them: and his disciples rebuked those that brought them.
But when Jesus saw it, he was much displeased, and said unto them, Suffer the little children to come unto me, and forbid them not: for of such is the kingdom of God.
Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child, he shall not enter therein.
And he took them up in his arms, put his hands upon them, and blessed them."
(Mark 10:13-16)

"Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call."
(Acts 2:37-39)
